When compute fence did signal, compute ring cannot detect hardware hang
because its timeout value is set to be infinite by default.
In SR-IOV and passthrough mode, if user does not declare custome timeout
value for compute ring, then use gfx ring timeout value as default. So
that when there is a ture hardware hang, compute ring can detect it.

I assume that you move the code because previously SRIOV/passthrough
setting is not available yet?
But even with this here you can still remove the extra SRIOV check in
amdgpu_fence.c.
