[Intel-gfx] [PATCH] drm/i915: Fix logical inversion for gen4 quirking

[Chris Wilson]

The assertion that we want to make before disabling the pin of the pages
for the unknown swizzling quirk is that the quirk is indeed active.

Fixes: 2c3a3f44dc13 ("drm/i915: Fix pages pin counting around swizzle quirk")
Fixes: 957870f93412 ("drm/i915: Split out i915_gem_object_set_tiling()")
