MEDIUM: connection: always unset the transport layer upon close

Browse Source 
When calling conn_xprt_close(), we always clear the transport pointer
so that all transport layers leave the connection in the same state after
a close. This will also make it safer and cheaper to call conn_xprt_close()
multiple times if needed.
