CIFS: Fix some return values in case of error in 'crypt_message'
'rc' is known to be 0 at this point. So if 'init_sg' or 'kzalloc' fails, we
should return -ENOMEM instead.
Also remove a useless 'rc' in a debug message as it is meaningless here.
Fixes: 026e93dc0a3ee ("CIFS: Encrypt SMB3 requests before sending")
