afs: Fix server rotation's handling of fileserver probe failure
The server rotation algorithm just gives up if it fails to probe a fileserver. Fix this by rotating to the next fileserver instead. Fixes: d2ddc776a458 ("afs: Overhaul volume and server record caching and fileserver rotation") Signed-off-by: David Howells <dhowells@redhat.com>
