igt/kms_busy: Flush request queue when re-enabling hangcheck
Enabling hangcheck only takes effect at the start of a new request
queue. Before we re-enable hangcheck after our poking around, we
therefore need to wait until the gpu is idle otherwise the next test
will start without hangcheck and subsequently hang forever.
