[PATCH 1/3] Revert "SUNRPC: Ensure gss-proxy connects on setup"

[Wang Hai <wanghai38@huawei.com>]

This reverts commit 892de36fd4a98fab3298d417c051d9099af5448d.

In fact, gss-proxy can't respond to rpc_ping() at setup time.
After the timeout, rpc_ping() will return -EIO instead of -EOPNOTSUPP.
The reverted patch can't ensure that gssp connects to the service
at setup time.
