s3:smb2 fix smbd crash on premature end of smb2 conn (Bug 8286)

Browse Source 
when smbd tries to clean up locks after a premature end of a smb2
connection, lock_db has already been freed and so it crashes

this patch changes the order in which items are freed so that
lock_db is still around when it is needed

Jeremy, Metze, please check
