tests: Channel switch with HT40
ap_ht40_csa and ap_ht40_csa3 seem to show a cfg80211/mac80211 issue where a CSA from HT40+ to HT40- channel results in HT getting disabled due to cfg80211_chandef_compatible() check on c1->width == c2->width claiming that the new channel is not compatible. For now, comment out the FAIL case for these known issues to avoid constant failure for cases that are not wpa_supplicant/hostapd issues. Once the kernel side design has been reviewed, these error cases can be enabled here. Signed-off-by: Jouni Malinen <j@w1.fi>
