drm/amdgpu: skip mes self test after s0i3 resume for MES IP v11.0

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.
