SMB3: Add missing locks to protect deferred close file list

Browse source

[ Upstream commit ab9ddc87a9 ]

cifs_del_deferred_close function has a critical section which modifies
the deferred close file list. We must acquire deferred_lock before
calling cifs_del_deferred_close function.

Fixes: ca08d0eac0 ("cifs: Fix memory leak on the deferred close")
