madwifi: change wireless ifname numbering schema Instead of simply counting up until we hit a free iface, group ifnames by wiphy so that the first wlanX on a phy gets the phy number and following ifaces an index-suffix, e.g. ath0 for network 1 on phy 1 and ath0-1 for network 2 on phy 1. This fixes state var confusion when operating multiple radios and allows to reliably take down and restart one radio only, even if the number of networks changes in between. This should, along with other changes in LuCI, fix #10335.
