cifs: hide unused functions

Some functions are only referenced under an #ifdef, causing a harmless warning:

fs/cifs/smb2ops.c:1374:1: error: 'get_smb2_acl' defined but not used [-Werror=unused-function]

We could mark them __maybe_unused or add another #ifdef, I picked the second approach here.

Fixes b3fdda4d1e1b ("cifs: Use smb 2 - 3 and cifsacl mount options getacl functions")
