[Intel-gfx] [PATCH] drm/i915/guc: do not capture error state on exiting context

Capturing error state is time consuming (up to 350ms on DG2), so it should
be avoided if possible. Context reset triggered by context removal is a
good example.
With this patch multiple igt tests will not timeout and should run faster.
