afs: Fix ignored callbacks over ipv4
When searching for a matching peer, all addresses need to be searched,
not just the ipv6 ones in the fs_addresses6 list.
Given that the lists no longer contain addresses, there is little
reason to splitting things between separate lists, so unify them
into a single list.
When processing an incoming callback from an ipv4 address, this would
lead to a failure to set call->server, resulting in the callback being
ignored and the client seeing stale contents.
Fixes: 72904d7b9bfb ("rxrpc, afs: Allow afs to pin rxrpc_peer objects")
