Dennis Li 53b3f8f40e drm/amdgpu: refine codes to avoid reentering GPU recovery ...

if other threads have holden the reset lock, recovery will
fail to try_lock. Therefore we introduce atomic hive->in_reset
and adev->in_gpu_reset, to avoid reentering GPU recovery.

v2:
drop "? true : false" in the definition of amdgpu_in_reset
