[Intel-gfx] [PATCH] drm/i915: Only dump GPU state on set-wedged if interesting

[Chris Wilson]

As we may frequently mark the device as wedged to flush requests off it
during the normal course of events, quite often we have a large state
dump that is of no interest. Don't bother dumping it all if the engines
are all idle.
