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

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.
