When a network is moved or reconfigured on the different channel, there can be multiple BSSes with the same BSSID and SSID in scan result before the old one expires. Then, it can cause cfg80211_connect_result to map current_bss to a bss with the wrong channel. Let mwifiex_cfg80211_assoc return the selected BSS and then the caller can report it cfg80211_connect_bss.
