drm/amdgpu: add codes to capture invalid hardware access when recovery
When recovery thread has begun GPU reset, there should be not other
threads to access hardware, otherwise system randomly hang.
v2 (chk): rewritten from scratch, use trylock and lockdep instead of
hand wiring the logic.
v3: add in_irq check
v4: change to check in_task
