However, calling functions such as ieee80211_beacon_get result in the rate_control_get_rate function getting called, which is accessing (in this case uninitialized) rate control structures unconditionally. Fix by exiting the function before setting the rates for HW with IEEE80211_HW_HAS_RATE_CONTROL set. The initialization of the ieee80211_tx_info struct is intentionally still executed.
