Fix channel switch without 'ht' for HE and EHT modes in 2.4 GHz band

Browse source 
hostapd_cli chan_switch command fails in 2.4 GHz band for HE and EHT
modes if the user does not explicitly specify 'ht' option in the
command.

For example:
"hostapd_cli -i wlan2 chan_switch 10 2412 sec_channel_offset=0 \
 center_freq1=2412 bandwidth=20 blocktx he"

Fix this by enabling HT by default if HE is enabled in the 2.4 GHz and 5
GHz bands. Similarly, enable VHT by default when HE is enabled in the 5
GHz band.
