drm/amdgpu: fix race between pstate and remote buffer map
Vega20 arbitrates pstate at hive level and not device level. Last peer to
remote buffer unmap could drop P-State while another process is still
remote buffer mapped.
With this fix, P-States still needs to be disabled for now as SMU bug
was discovered on synchronous P2P transfers. This should be fixed in the
next FW update.
