afs: Use the per-peer app data provided by rxrpc
Make use of the per-peer application data that rxrpc now allows the
application to store on the rxrpc_peer struct to hold a back pointer to the
afs_server record that peer represents an endpoint for.
Then, when a call comes in to the AFS cache manager, this can be used to
map it to the correct server record rather than having to use a
UUID-to-server mapping table and having to do an additional lookup.
