Trond Myklebust dbe6974a39 SUNRPC: Don't call connect() more than once on a TCP socket ...

commit 89f42494f9 upstream.

Avoid socket state races due to repeated calls to ->connect() using the
same socket. If connect() returns 0 due to the connection having
completed, but we are in fact in a closing state, then we may leave the
XPRT_CONNECTING flag set on the transport.
