[Intel-gfx] [PATCH 2/4] drm/i915/execlists: Reset queue_priority on cancellation

[Chris Wilson]

If we have an available execlists port, the queue_priority should be
INT_MIN to allow immediate direct submission. As we clear the ports in
execlists_cancel_port_requests(), we should then reset queue_priority to
show the available space.
