SUNRPC: Teach the RPC portmapper to use the new rpc_peeraddr() API.
Hide the details of how the RPC client stores remote peer addresses from
the RPC portmapper.
Test plan:
Destructive testing (unplugging the network temporarily). Connectathon
with UDP and TCP. NFSv2/3 and NFSv4 mounting should be carefully checked.
