Subject: Fix for panic in endpoint.Close().

When sending a RST on shutdown we need to double check the
state after acquiring the work mutex as the endpoint could
have transitioned out of a connected state from the time
we checked it and we acquired the workMutex.

I added two tests but sadly neither reproduce the panic. I am
going to leave the tests in as they are good to have anyway.
