drm/xe/pf: Fix VF config validation on multi-GT platforms

When validating VF config on the media GT, we may wrongly report
that VF is already partially configured on it, as we consider GGTT
and LMEM provisioning done on the primary GT (since both GGTT and
LMEM are tile-level resources, not a GT-level).

This will cause skipping a VF auto-provisioning on the media-GT and
in result will block a VF from successfully initialize that GT.

Fix that by considering GGTT and LMEM configurations only when
checking if a VF provisioning is complete, and omit GGTT and LMEM
when reporting empty/partial provisioning.

Fixes: 234670c ("drm/xe/pf: Skip fair VFs provisioning if already provisioned")
