SUNRPC: Deal with the lack of a SYN_SENT sk->sk_state_change callback...

BugLink: http://bugs.launchpad.net/bugs/793702

commit fe19a96b10032035a35779f42ad59e35d6dd8ffd upstream.

The TCP connection state code depends on the state_change() callback
being called when the SYN_SENT state is set. However the networking layer
doesn't actually call us back in that case.
