drm/amd/amdgpu: fix corner case in SRIOV tdr
[Why] In SRIOV multi-vf, after using ordered workqueue for tdr, there could be a chance that a ring timeout continuously makes an innocent ring timeout. [How] 1. Use advance tdr mode in SRIOV as default 2. Use mdelay in flr work to make sure the waiting won't exceeds ring timeout.
