The request sequence for SVC protocol is fixed at least upto SVC_HELLO request. The first request has to be Protocol Version, followed by SVC_HELLO. Any other request can follow them, but these two. Add another field in 'struct gb_svc' that keeps track of current state of the protocol driver. It tracks only upto SVC_HELLO, as we don't need to track later ones. Also add a comment, about the order in which the requests are allowed and why a race can't happen while accessing 'state'. This removes the WARN_ON() in gb_svc_hello() as we track state transition with 'state' field. This also fixes a crash, when the hotplug request is received before fully initializing the svc connection. The crash mostly happens while accessing svc->connection->bundle, which is NULL, but can happen at other places too, as svc connection isn't fully initialized.
