cifs: Replace SendReceiveBlockingLock() with SendReceive() plus flags

Replace the smb1 transport's SendReceiveBlockingLock() with SendReceive()
plus a couple of flags.  This will then allow that to pick up the transport
changes there.

The first flag, CIFS_INTERRUPTIBLE_WAIT, is added to indicate that the wait
should be interruptible and the second, CIFS_WINDOWS_LOCK, indicates that
we need to send a Lock command with unlock type rather than a Cancel.

send_lock_cancel() is then called from cifs_lock_cancel() which is called
from the main transport loop in compound_send_recv().

[!] I *think* the error code handling is probably right.
