cifs: check for bytes_remaining going to zero in CIFS_SessSetup
commit fcda7f4578bbf9717444ca6da8a421d21489d078 upstream.
It's possible that when we go to decode the string area in the
SESSION_SETUP response, that bytes_remaining will be 0. Decrementing it at
that point will mean that it can go "negative" and wrap. Check for a
bytes_remaining value of 0, and don't try to decode the string area if
that's the case.
