Fix handling of beacon frames by stations while they're associated.
Changes in the ERP information element and in the capinfo field were not
detected properly, so the drivers were not able to adjust their settings
(like short slot time, short preamble, protection mode etc...)
dynamically. Should fix BSS mode with both 802.11b and 802.11g stations.
