Doing a channel switch via hostapd_cli seems to update
the new channel context for each VAP's appropriately as below
in 'ath10k_mac_update_vif_chan', hence we can safely suppress the
warning that shows up during this operation and dump the warning only
if no vaps are available for channel switch
hostapd_cli -i wlan0 chan_switch 5 5200
OK
