drm/xe/vf: Unblock xe_rtp_process_to_sr for VFs

In commit 9632dfb0def4 ("drm/xe/vf: Don't run any save-restore
RTP actions if VF") we disabled processing of all RTP rules if
we were running as a VFs, since many of the RTP actions were
trying to access registers unaccessible for VFs.

This also included all of LRC WA rules, since some of them were
implemented in a way that required RMW pattern.

Now, as we can program LRC WAs without accessing such registers
from the driver, relying on the MI_MATH instruction instead, we
can unblock xe_rtp_process_to_sr() for VFs.
