drm/xe/pf: Encode scheduling priority KLV if needed

Browse source

After a reset we missed to reprovision VFs scheduling priority config.
But as of today, the GuC firmware allows to change scheduling priority
using config SCHED_PRIORITY KLV only for the PF and configuration of
all VFs relies on the previously applied value of the SCHED_IF_IDLE
policy. Use this policy value to check and decide whether we need to
encode VF priority KLV while reprovisioning this VF.
