drm/amdgpu: always sending PSP messages LOAD_ASD and UNLOAD_TA

Browse source

We allow sending PSP messages LOAD_ASD and UNLOAD_TA without
acquiring a lock in drm_dev_enter during driver unload
because we must call drm_dev_unplug as the beginning
of unload driver sequence.
Added WARNING if other PSP messages are sent without a lock.
After this commit, the following commands would work
 -sudo modprobe -r amdgpu
 -sudo modprobe amdgpu
