i915/guc/reset: Make __guc_reset_context aware of guilty engines
There are 2 ways an engine can get reset in i915 and the method of reset
affects how KMD labels a context as guilty/innocent.
(1) GuC initiated engine-reset: GuC resets a hung engine and notifies
KMD. The context that hung on the engine is marked guilty and all other
contexts are innocent. The innocent contexts are resubmitted.
(2) GT based reset: When an engine heartbeat fails to tick, KMD
initiates a gt/chip reset. All active contexts are marked as guilty and
discarded.
In order to correctly mark the contexts as guilty/innocent, pass a mask
of engines that were reset to __guc_reset_context.
