mac80211: properly drop the connection in case of invalid CSA IE

Browse source

In case the frequency is invalid, ieee80211_parse_ch_switch_ie
will fail and we may not even reach the check in
ieee80211_sta_process_chanswitch. Drop the connection
in case ieee80211_parse_ch_switch_ie failed, but still
take into account the CSA mode to remember not to send
a deauth frame in case if it is forbidden to.
