SUNRPC: Fix a missing "break" option in xs_tcp_setup_socket()

In the case of -EADDRNOTAVAIL and/or unhandled connection errors, we want
to get rid of the existing socket and retry immediately, just as the
comment says. Currently we end up sleeping for a minute, due to the missing
"break" statement.
