mac80211: eliminate IBSS warning in rate_lowest_index()
An IBSS station is added in prepare_for_handlers where the rate scaling was
initialized only with single rate matching the received packet.
The correct rate scale information should be updated only in
ieee80211_rx_bss_info function where beacon is parsed. Because
of coding error the rate info was left untouched.
If a beacon has triggered the connection the rate remined 1Mbps.
This patch fixes this coding error
