cifs: reschedule periodic query for server interfaces

Today, we schedule periodic query for server interfaces
once every 10 minutes once a tree connection has been
established. Recent change to handle disabling of
multichannel disabled this delayed work.

This change reenables it following a reconnect, and
the server advertises multichannel.
