PNP: skip UNSET MEM resources as well as DISABLED ones
We don't need to reserve "unset" resources. Trying to reserve them results in messages like this, which are ugly but harmless: system 00:08: iomem range 0x0-0x0 could not be reserved Future PNP patches will remove use of IORESOURCE_UNSET, but we still need it for now.
