Bharath SM 59a556aebc SMB3: drop reference to cfile before sending oplock break 
In cifs_oplock_break function we drop reference to a cfile at
the end of function, due to which close command goes on wire
after lease break acknowledgment even if file is already closed
by application but we had deferred the handle close.
If other client with limited file shareaccess waiting on lease
break ack proceeds operation on that file as soon as first client
sends ack, then we may encounter status sharing violation error
because of open handle.
Solution is to put reference to cfile(send close on wire if last ref)
and then send oplock acknowledgment to server.

Fixes: 9e31678fb4 ("SMB3: fix lease break timeout when multiple deferred close handles for the same file.")
