[Intel-gfx] [PATCH] drm/i915/guc: Report error on invalid reset notification

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

Don't silently drop reset notifications from the GuC. It might not be
safe to do an error capture but we still want some kind of report that
the reset happened.
