John Crispin 49ec79e126 mac80211: fix fallback to macaddr
If '/sys/class/ieee80211/phyN' is not a symlink, the call to readlink
produces either an empty path (if /sys/class/ieee80211/phyN/device doesn't
exist) or a path that begins with '/sys/class/ieee80211' (which does not
work with the subsequent line to strip '/sys/devices' from the beginning of
the path).  Modify the checks to detect these conditions, and fallback to
using the macaddr.
