Subject: drm/i915: Let execlist_update_context() cover !FULL_PPGTT mode.

From: Zhi Wang <[email protected]>

commit 26d12c619476ccbc6725aa4a17dcb1d41d5774e7 upstream.

execlist_update_context() will try to update PDPs in a context before a ELSP submission only for full PPGTT mode, while PDPs was populated during context initialization. Now the latter code path is removed. Let execlist_update_context() also cover !FULL_PPGTT mode.
