Chris Wilson af23facc38 drm/i915: Check current i915_vma.pin_count status first on unbind 
Do an early rejection of a i915_vma_unbind() attempt if the i915_vma is
currently pinned, without waiting to see if the inflight operations may
unpin it. We see this problem with the shrinker trying to unbind the
active vma from inside its bind worker:
