commit 8660495a9c5b9afeec4cc006b3b75178f0fb2f10 upstream.
MES is part of gfxoff and MES suspend and resume are skipped for S0i3. But the mes_self_test call path is still in the amdgpu_device_ip_late_init. it's should also be skipped for s0ix as no hardware re-initialization happened.
Besides, mes_self_test will free the BO that triggers a lot of warning messages while in the suspend state.
