This reverts commit 892de36fd4a98fab3298d417c051d9099af5448d.

The gssproxy server is unresponsive when it calls into the kernel to
start the upcall service, so it will not reply to our RPC ping at all.

Reported-by: "J.Bruce Fields" <bfields@fieldses.org>
Fixes: 892de36fd4a9 ("SUNRPC: Ensure gss-proxy connects on setup")
