drm/imagination: Fix returned size for DRM_IOCTL_PVR_DEV_QUERY

For a few subtypes of DRM_IOCTL_PVR_DEV_QUERY, driver was overriding
the returned size unconditionally. This would have resulted in
increase of reported size beyond the amount of data returned to
userspace when args->size < size of query structure.

Updated behaviour matches with the description of
drm_pvr_ioctl_dev_query_args.size and written byte length.
None of the structures of DRM_IOCTL_PVR_DEV_QUERY changed after addition,
so change will not break any compatibility with earlier version.

Fixes: f99f5f3ea7ef ("drm/imagination: Add GPU ID parsing and firmware loading")
Fixes: ff5f643de0bf ("drm/imagination: Add GEM and VM related code")
