Allow HE-without-VHT to add the Channel Switch Wrapper element

Browse Source 
Modify the check for VHT to include an option for HE in
hostapd_eid_wb_chsw_wrapper() and its callers to allow the Channel
Switch Wrapper element with the Wide Bandwidth Channel Switch subelement
to be included in Beacon and Probe Response frames when AP is operating
in HE mode without VHT.
