[PATCH 08/12] drm/i915/selftests: Remove redundant set-to-gtt-domain

[Tvrtko Ursulin <tvrtko.ursulin@xxxxxxxxxxxxxxx>]

From: Chris Wilson <chris@xxxxxxxxxxxxxxxxxx>

Since the vma's backing store is flushed upon first creation, remove the
manual calls to set-to-gtt-domain.

v2 (Tvrtko):
 * Rebase.
