drm/amdgpu: don't use MM idle_work for SRIOV(v2)
SRIOV doesn't give VF cg/pg feature so the MM's idle_work
is skipped for SR-IOV
v2:
remove superfluous changes
since idle_work is not scheduled for SR-IOV so the condition
check for SR-IOV inside idle_work also can be dropped
v3:
drop the SRIOV check in amdgpu_vce/uvd_suspend
