Subject: [PATCH 2/3] Revert "Revert "SUNRPC: attempt AF_LOCAL connect on setup""

This reverts commit a3d0562d4dc039bca39445e1cddde7951662e17d.

There is currently no better way to ensure that gss-proxy connects when
setup. Therefore, it is still necessary to connect in the construction.
The mechanism to safely tear xprt down needs to be implemented later.
