gpu tlb flush is skipped if reset sem is held, it makes
mes_self_test fail since it involves add_hw_queue/remove_hw_queue
which needs tlb flush functional. Remove mes_self_test in gpu
recover sequence.

Oh, the TLB issue is actually only the tip of the iceberg. That only worked by coincident.

During GPU reset you are not allowed to make any memory allocation or otherwise you can run into a deadlock. So doing a MES test is a complete no-go in the first place.


This patch is to fix the recover failure in gfx11.
