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

[Andrzej Hajda <andrzej.hajda@intel.com>]

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.
