drm/i915: Fix a lockdep warning at error capture

For some platfroms we use stop_machine version of
gen8_ggtt_insert_page/gen8_ggtt_insert_entries to avoid a
concurrent GGTT access bug but this causes a circular locking
dependency warning:

  Possible unsafe locking scenario:
        CPU0                    CPU1
        ----                    ----
   lock(&ggtt->error_mutex);
                                lock(dma_fence_map);
                                lock(&ggtt->error_mutex);
   lock(cpu_hotplug_lock);

Fix this by calling gen8_ggtt_insert_page/gen8_ggtt_insert_entries
directly at error capture which is concurrent GGTT access safe because
reset path make sure of that.

v2: Fix rebase conflict and added a comment.
