[PATCH] drm/i915/guc: Fix missing enable of Wa_14019159160 on ARL

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

The previous update to enable the workaround on ARL only changed two
out of three places where the w/a needs to be enabled. That meant the
GuC side was operational but not the KMD side. And as the KMD side is
the trigger, it meant the w/a was not actually active. So fix that.
