When going on a waitinglist, the HTTP1 step counter was set to S_STP_H1BUSY to allow conditions to be checked on return specific to having been on a waitinglist. Though the step counter was set after entering the waitinglist, and if the session was rescheduled immediately on another thread a race opened which would mess up the state handling. Fix this by elliminating the S_STP_H1BUSY step, and having condition checks on req->hash_objhead in the S_STP_H1PROC state to handle the waitinglist return specific checks. The panic output has been changed to include the req->hash_objhead pointer if set. This exposes the waitinglist condition in the panic output which would otherwise be hidden by the removal of the S_STP_H1BUSY step. Fixes: #2117
