[Intel-gfx] [PATCH 2/2] drm/i915: Complete pending resets before get-reset-stats ioctl

[Chris Wilson]

The get-reset-stats ioctls wasn't waiting for a pending reset before
reporting its statistics, and so was ignoring a hang generated by the
context that should have been reported against said context.
