accel/ivpu: Trigger device recovery on engine reset/resume failure
[ Upstream commit a47e36dc5d90dc664cac87304c17d50f1595d634 ]
Trigger full device recovery when the driver fails to restore device state
via engine reset and resume operations. This is necessary because, even if
submissions from a faulty context are blocked, the NPU may still process
previously submitted faulty jobs if the engine reset fails to abort them.
Such jobs can continue to generate faults and occupy device resources.
When engine reset is ineffective, the only way to recover is to perform
a full device recovery.
