drm/xe/pf: Restart VFs provisioning after GT reset

drm/xe/pf: Restart VFs provisioning after GT reset

Any prior configurations pushed to the GuC are lost when the GT
is reset. Push again all non-empty VF configurations to the GuC
as part of the GuC reset procedure.

This will also help restore early manual provisioning, when the
PF was in the meantime suspended and then resumed.
