drm/amdgpu/mes12: drop amdgpu_mes_suspend()/amdgpu_mes_resume() calls

They are noops on GFX12.  There is no suspend/resume all support
in firmware so the function doesn't do anything.  KFD already
handles its own queues and they should already be unmapped at this
point so even if this runs, it's not doing anything.
