band: fix HT40+/- checks when creating chandef

Browse Source 
The HT40+/- flags were reversed when checking against the 802.11
behavior flags.

HT40+ means the secondary channel is above (+) the primary channel
therefore corresponds to the PRIMARY_CHANNEL_LOWER behavior. And
the opposite for HT40-.
