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.
