mac80211: make sure existing iface belongs to correct (fullmac) phy
Some FullMAC cfg80211 wireless devices do not support virtual interfaces, hence there is script logic to keep the existing network device. Improve this to support renaming the interface if needed and make sure the existing interface actually belongs to the right phy. Change calls to 'iw' to avoid outputing warnings and errors to not confuse users of such devices. Also bump PKG_RELEASE which has been forgotten in the previous two mac80211 changes.
