Revert "SUNRPC: attempt AF_LOCAL connect on setup"

commit 9481858df7ce028fde481c995723e113faeaecd1 upstream.

This reverts commit cad718d9315db3f05d5c39bd1db021aef0d463c5.

We must not try to connect the socket while the transport is under
construction, because the mechanisms to safely tear it down are not in
place. As the code stands, we end up leaking the sockets on a connection
error.
