wpa_supplicant: Add channel 140 to ht40plus allowed list for mesh/IBSS

Browse source 
When channel 140 is configured in mesh, interface fails to come up due
to channel bond (136,140). Since Channel 136 is not HT40+ capable,
validation for HT channel bonding fails when it checks whether first
channel in the bond (channel 136) is HT40+ capable.

In mesh, during channel setup, secondary channel offset for the
configured channel will be selected as +1 if primary channel is capable
of HT40+. In current code, channel 140 is not allowed as HT40+ and hence
secondary channel offset is selected as -1, which makes 136 as secondary
channel. But channel 136 is not HT40+ supported and fails in channel
bonding validation.

Add 140 to HT40+ allowed list as HT40+ is supported for the channel.
