I can replace all the cifs_dbg() calls in smb2_check_message() easily,
and in parse_server_interfaces() with just a little work, but the others
would require plumbing in either the server or ses variables to the
functions.
I'll change the cifs_dbg() I'm adding in smb2_check_message, and
then make a couple follow-up patches to convert the existing ones.
