cifs: make sure server interfaces are requested only for SMB3+
Some code paths for querying server interfaces make a false
assumption that it will only get called for SMB3+. Since this
function now can get called from a generic code paths, the correct
thing to do is to have specific handler for this functionality
per SMB dialect, and call this handler.
This change adds such a handler and implements this handler only
for SMB 3.0 and 3.1.1.
