drm/xe/pf: Reprovision policy settings after GT reset

Browse Source 
In addition to the reprovisioning of individual VFs configurations,
we should also reprovision GuC global policy settings. Note that we
already had a draft function for that but we missed to call it once
we started handling GT reset. Reuse it now but don't take extra RPM
as this is now a caller responsibility and drop unused parameter.
