[PATCH 15/27] afs: Fix handling of CB.ProbeUuid cache manager op

[David Howells]

The AFS filesystem driver is handling the CB.ProbeUuid request incorrectly.
The UUID presented in the request is that of the cache manager, not the
fileserver, so afs_deliver_cb_probe_uuid() shouldn't be using that UUID to
look up the server.

Fix this by looking up the server by address instead.
