gpu: nvgpu: get intr mask for an active_engine_id
This is needed for t19x during eng preempt done polling.
E.g. copy engine (CE) stall interrupt should not prevent GR
from finishing preemption. In order to check if current stall
interrupt is valid for the engine being polled for
preemption completion, function to provide engine
intr mask is needed. With this, polling code can make sure
there are no stall interrupts pending for the engine being
polled for preemption done. If stall interrupts
are pending for an engine, preemption will never finish.
