[PATCH v4 1/7] resource: Mark free space assigned

[Ilpo Järvinen]

Free space ranges are (part of) assigned ranges. Since new resources
have IORESOURCE_UNSET, the flag gets copied also to full_avail.flags,
which hampers printing them with %pR.

Clear IORESOURCE_UNSET for the free space indicator resource.
