Chris Wilson 608c1a526c drm/i915: Recover all available ringbuffer space following reset
Having flushed all requests from all queues, we know that all
ringbuffers must now be empty. However, since we do not reclaim
all space when retiring the request (to prevent HEADs colliding
with rapid ringbuffer wraparound) the amount of available space
on each ringbuffer upon reset is less than when we start. Do one
more pass over all the ringbuffers to reset the available space
