drm/amd: Skip power ungate during suspend for VPE
During the suspend sequence VPE is already going to be power gated as part of vpe_suspend(). It's unnecessary to call during calls to amdgpu_device_set_pg_state(). It actually can expose a race condition with the firmware if s0i3 sequence starts as well. Drop these calls.
