[PATCH] cifs: remove dead code

[Arnd Bergmann]

cifs provides two dummy functions 'sess_auth_lanman' and
'sess_auth_kerberos' for the case in which the respective
features are not defined. However, the caller is also under
an #ifdef, so we just get warnings about unused code:

fs/cifs/sess.c:1109:1: warning: 'sess_auth_kerberos' defined but not used [-Wunused-function]
sess_auth_kerberos(struct sess_data *sess_data)

Removing the dead functions gets rid of the warnings without
any downsides that I can see.
