Btw, if the concern is the gfx_late_init failure caused by incorrect setting in
IFWI. @Feng, Kenneth already have a workaround.

[AMD Official Use Only - General]
amdgpu_ras_feature_enable won't send RAS command to firmware if it is invoked
from guest side. The change seems unnecessary.

In sriov guest side doesn't need init ras feature, so skip it.
