[Intel-gfx] [PATCH] drm/i915: Remove vestigal i915_gem_context locals from cmdparser

[Chris Wilson]

The use GEM context itself was removed in commit cd30a5031704
("drm/i915/gem: Excise the per-batch whitelist from the context"), but
the locals were left in place as an oversight. Remove the parameters and
clean up.
