P2P: Fix secondary channel selection for HT40 

wpas_p2p_get_ht40_mode() used blacklist approach (bw != BW20) to find
the relevant op_class, but didn't take into account other non-BW40
cases, like BW80, that had been added to the bw enum after the initial
implementation. Fix this by looking for the specific BW40 bw cases.
