drm/xe/vf: Stop applying save-restore MMIOs if VF

Browse source

Currently we are blocking processing of all save-restore rules
by the VFs inside the xe_rtp_process_to_sr() function, but we
want to unblock that to allow processing of the LRC WA rules.

To avoid hitting WARNs about reading an inaccessible registers by
the VFs, stop applying save-restore MMIOs action if VF, without
relying that SR list will be always empty for the VF.
