nl80211: Support network hierarchy of a master interface under bridge

Browse source 
Since commit cb05808c46 ('nl80211: Generic
Linux master interface support for hostapd'), hostapd is listening for
EAPOL frames on any master which the interface is enslaved under.

This commit allows hostapd to support network hierarchy in which the
interface is enslaved under some master which in turn is enslaved under
a bridge.
