libcli/smb: Ensure we call tevent_req_nterror() on failure

Commit 3594c3ae202688fd8aae5f7f5e20464cb23feea9 added a NULL check for
'inhdr', but it meant we didn't always call tevent_req_nterror() when we
should.

Now we handle connection errors. We now also set an error status if the
NULL check fails.

I noticed this when an ECONNRESET error from a server refusing SMB1
wasn't handled, and the client subsequently hung in epoll_wait().

smbd: directly pass fsp to SMB_VFS_FGETXATTR() in fget_ea_dos_attribute()

We're now consistently passing the base_fsp to SMB_VFS_FSET_DOS_ATTRIBUTES(), so
we don't need to check for a stream_fsp here anymore.

Additionally vfs_default will assert a non-stream fsp inside
vfswrap_fgetxattr(), so in case any caller wrongly passes a stream fsp, this is
caught in vfs_default.

smbd: add and use vfs_fget_dos_attributes()

s3/smbd: Use after free when iterating smbd_server_connection->connections

In SMB2 smbd_smb2_tree_connect() we create a new conn struct
inside make_connection_smb2() then move the ownership to tcon using:

        tcon->compat = talloc_move(tcon, &compat_conn);

so the lifetime of tcon->compat is tied directly to tcon.

Inside smbXsrv_tcon_disconnect() we have:

 908                 ok = chdir_current_service(tcon->compat);
 909                 if (!ok) {
 910                         status = NT_STATUS_INTERNAL_ERROR;
 911                         DEBUG(0, ("smbXsrv_tcon_disconnect(0x%08x, '%s'): "
 912                                   "chdir_current_service() failed: %s\n",
 913                                   tcon->global->tcon_global_id,
 914                                   tcon->global->share_name,
 915                                   nt_errstr(status)));
 916                         tcon->compat = NULL;
 917                         return status;
 918                 }
 919
 920                 close_cnum(tcon->compat, vuid);
 921                 tcon->compat = NULL;

If chdir_current_service(tcon->compat) fails, we return status without ever having
called close_cnum(tcon->compat, vuid), leaving the conn pointer left in the linked
list sconn->connections.

The caller frees tcon and (by ownership) tcon->compat, still leaving the
freed tcon->compat pointer on the sconn->connections linked list.

When deadtime_fn() fires and walks the sconn->connections list it
indirects this freed pointer. We must call close_cnum() on error also.

s3: smbd: Add IS_VETO_PATH checks to openat_pathref_fsp_case_insensitive().

Returns NT_STATUS_OBJECT_NAME_NOT_FOUND for final component.

Note we have to call the check before each call to
openat_pathref_fsp(), as each call may be using a
different filesystem name. The first name is the
one passed into openat_pathref_fsp_case_insensitive()
by the caller, the second one is a name retrieved from
get_real_filename_cache_key(), and the third one is the name
retrieved from get_real_filename_at(). The last two
calls may have demangled the client given name into
a veto'ed path on the filesystem.
