qcacld-3.0: Do 11ac override only if channel list has 5Ghz channel(s)

Browse source 
If 11ac override is enabled, change hw moed to 11ac and channel width
to the value defined in vht channel width ini. If channel list received
from hostapd contains only 2.4 Ghz channels, mismatch happens as hw mode
is 11ac but the channel list contains only 2.4 Ghz channels and no 5Ghz
channel.

Do 11ac override only when the channel list received from hostapd contains
5Ghz channel(s).
