[PATCH v5 10/23] drm/xe/query: Report hwconfig size as 0 if primary GT is disabled

[Matt Roper <matthew.d.roper@intel.com>]

The hwconfig table is part of the primary GT's GuC firmware.  If the
primary GT is disabled, the hwconfig is unavailable and should be
reported to userspace as having size 0.
