[Intel-gfx] [PATCH 3/3] drm/i915: Reduce GPU error capture mutex hold time

Shrink the hold time for the error capture mutex to just around the acquire/release of the PTE used for reading back the object via the Global GTT. For platforms that do not need the GGTT read back, we can skip the mutex entirely and allow concurrent error capture. Where we do use the GGTT, by rest
