Subject: CIFS: Fix some return values in case of error in 'crypt_message'

From: Christophe Jaillet <[email protected]>

commit 517a6e43c4872c89794af5b377fa085e47345952 upstream.

'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.
