drm/xe/pf: Check EQ/PT/PRIO when testing VF config

In addition to the hard resources (like GGTT, CTXs, DBs) we should
also check if VF was already configured (by sysfs or debugfs) with
optional parameters like execution quantum (EQ), preemption timeout
(PT) or scheduling priority (PRIO) as otherwise we might miss to
send to the GuC updated latest values after a resume or GT reset.
