drm/amdgpu: skip gfx switch_power_profile during GPU reset

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: skip gfx switch_power_profile during GPU reset

During resume from GPU reset, the gfx idle work may invoke switch_power_profile
before the reset completes. This causes the following assert error because the
register access occurs without first releasing the GPU reset semaphore:
