Fix channel switch wrapper when switching from HT to VHT/HE

Browse source 
Because ieee80211ac and ieee80211ax were not updated before channel
switch is done, hostapd didn't build the Channel Switch Wrapper element
when it switched from HT to bandwidth more than 40 MHz of VHT/HE. fix
this by allowing hostapd_eid_wb_chsw_wrapper() to determine internally
when the element needs to be added based on the new channel instead of
the old configuration.
