drm/i915: Zap mmaps of objects before unbinding them from the GTT. Otherwise, some other userland writing into its buffer may race to land writes either after the CPU thinks it's got a coherent view, or after its GTT entries have been redirected to point at the scratch page. Either result is unpleasant. Signed-off-by: Eric Anholt <eric@anholt.net>
