drm/i915/guc: Add work queue to trigger a GT reset

Browse source

The G2H handler needs to be flushed during a GT reset but a G2H
indicating engine reset failure can trigger a GT reset. Add a worker to
trigger the GT rest when an engine reset failure is received to break
this circular dependency.

v2:
 (John Harrison)
  - Store engine reset mask
  - Fix typo in commit message
v3:
 (John Harrison)
  - Fix another typo in commit message
  - s/reset_*/reset_fail_*/
