smbd: call locking_close_file() while still holding a glock on the locking.tdb record

smbd: use share_mode_do_locked_brl()
Fix a deadlock that can happen if two clients happen to open and byte-range-lock
two different files whos record in locking.tdb and brlock.tdb happen to sit on
the same hashchain.
The deadlock was introduced by commit
680c7907325b433856ac1dd916ab63e671fbe4ab. Before, we used share_mode_do_locked()
in do_lock() which meant we acquired a chainlock on locking.tdb before getting a
chainlock on brlock.tdb via brl_get_locks_for_locking(), so the TDB chainlock
order invariant was always uphold.
The following race between specific client requests lead to the deadlock.
Client A) issues a byte-range-lock request on a file:
A1) glock locking.tdb (via _share_mode_do_locked_vfs_allowed())
A2) chainlock brlock.tdb (via brl_lock())
A3) attempt to chainlock locking.tdb (via share_mode_g_lock_dump())
[1]
Client B) opens a different (!) file:
B1) glock and chainlock locking.tdb (via _share_mode_entry_prepare_lock())
B2) attempt to chainlock brlock.tdb (via file_has_brlocks())
[2]
The glock from A1 is per record and hence doesn't synchronize with the glock
from B1 as it is for a different file and hence a different record, subsequently
A2 and A3 violate the lock order constraint
To avoid the chainlock lock order violation in the second client we modify the
br-lock code to not take the brlock.tdb chainlock from step A2 via
br_get_locks() for the whole time we process the request. Instead we just fetch
the br-locks via br_get_locks_readonly(), so when running into
contend_level2_oplocks_begin_default() to check for leases and looking into
locking.tdb we don't hold a brlock.tdb chainlock.
Or im simpler terms, we only ever take at most one low-level TDB chainlock at a
time:
Byte-range-lock code calls share_mode_do_locked_brl(..., cb_fn, ...):
1) chainlock locking.tdb
2) glock locking.tdb (via share_mode_do_locked_vfs_allowed())
3) chainunlock locking.tdb
4) share_mode_do_locked_brl_fn() -> brl_get_locks_readonly_parse():
a) chainlock brlock.tdb
b) parse record and store in-memory copy
c) chainunlock brlock.tdb
5) run cb_fn()
6) chainlock brlock.tdb:
a) br_lck->record = dbwrap_fetch_locked(brlock_db, ...)
b) store modifed br_lck from 5) via byte_range_lock_flush()
7) chainunlock brlock.tdb
8) chainlock locking.tdb
9) gunlock locking.tdb
10) chainunlock locking.tdb
All access to brlock.tdb is synchronized correctly via glocks on the locking.tdb
record of the file (step 3)), so operations still appear atomic to clients.
As a result of using share_mode_do_locked_brl(), the functions do_[un]lock() ->
brl_[un]lock() now loop over the same br_lck object in memory, avoiding
repeatedly fetching and storing the locks per loop.
