Chris Wilson c6eeb4797e drm/i915: Reduce presumption of request ordering for barriers 
Currently we assume that we know the order in which requests run and so
can determine if we need to reissue a switch-to-kernel-context prior to
idling. That assumption does not hold for the future, so instead of
tracking which barriers have been used, simply determine if we have ever
switched away from the kernel context by using the engine and before
idling ensure that all engines that have been used since the last idle
are synchronously switched back to the kernel context for safety (and
else of shrinking memory while idle).

v2: Use intel_engine_mask_t and ALL_ENGINES
