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.
