nl80211: restore iterating over all devices in nl80211_phy2ifname()
This reverts to the earlier behaviour, because:
* phys can be renamed, which breaks hardcoding "phy%d"
* /sys/class/ieee80211/*/device can return networks of other phys,
since "device" is a symlink which can have multiple phys
The earlier behaviour fixes both points.
