In the patch about advanced TDR mode, we force to always set
amdgpu_gpu_recovery=2 under SRIOV. This is not ideal, since we
may want to revert back to use the legacy TDR routine.
Therefore, we only set amdgpu_gpu_recovery=2 when it is
configured as AUTO, which is the default

This is not reliable since after a FLR, MMSCH may report junk data.
