drm/i915: eliminate dead domain clearing on reset
The code itself is no longer accurate without updating once we have multiple address space since clearing the domains of every object requires scanning the inactive list for all VMs. "This code is dead. Just remove it rather than port it to vma." - Chris Wilson Recommended-by: Chris Wilson <chris@chris-wilson.co.uk> Signed-off-by: Ben Widawsky <benjamin.widawsky@intel.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
