Mika Kuoppala f8e4c5297f drm/i915: Fix cmd parser desc matching with masks 
[ Upstream commit e5f10d6385cda083037915c12b130887c8831d2b ]

Our variety of defined gpu commands have the actual
command id field and possibly length and flags applied.

We did start to apply the mask during initialization of
the cmd descriptors but forgot to also apply it on comparisons.

Fix comparisons in order to properly deny access with
associated commands.

v2: fix lri with correct mask (Chris)
