Chris Wilson 5424f5d794 drm/i915: Clear the GGTT_WRITE bit on unbinding the vma
While we do flush writes to the vma before unbinding (to make sure they
go through the right detiling register), we may also be concurrently
poking at the GGTT_WRITE bit from set-domain, as we mark all GGTT vma
associated with an object. We know this is for another vma, as we
are currently unbinding this one -- so if this vma will be reused, it
will be refaulted and have its dirty bit set before the next write.
