From: Oscar Mateo <oscar.ma...@intel.com>
Without this, i915_gem_context_free looks obfuscated. But, also, it
gives me the possibility to know which kind of context I am dealing
with at freeing time (at this point we only have fake and legacy hw
contexts, but soon we will have logical ring contexts as well).
