drm/xe/sriov: Disable SR-IOV if primary GT is disabled via configfs

Browse Source 
SR-IOV operation relies on the primary GT's GuC to operate (in both PF
and VF mode).  Don't enable the .has_sriov flag if the primary-GT was
disabled by configfs.

v2:
 - Move handling to xe_info_init().  (Michal)

v3:
 - Just update the .has_sriov flag in xe_info_init_early().  (Michal)

v4:
 - Drop unnecessary comment.  (Michal)
 - Flip condition order for consistency with other checks.  (Michal)
