intel: fix topology query
i915 will report ENODEV on generations prior to Haswell because there
is no point in reporting values on those. This is prior any fusing
could happen on parts with identical PCI ids.
This query call was previously only triggered on generations that
support performance queries, which happens to match generation for
which i915 reports topology, but the commit pointed below started
using it on all generations.
