[Nbd] [PATCH 5/6] nbd: handle ERESTARTSYS properly

We can submit IO in a processes context, which means there can be pending signals. This isn't a fatal error for NBD, but it does require some finesse. If the signal happens before we transmit anything then we are ok, just requeue the request and carry on. However if we've done a partial
