AP: Ensure ieee80211n_supported_ht_capab() gets called to check ht caps

ieee80211n_supported_ht_capab is called after ieee80211n_check_40mhz in
function hostapd_check_ht_capab. ieee80211n_check_40mhz can return 1 in
a valid scenario where the initialization is completed in a callback. In
this case ieee80211n_supported_ht_capab is skipped and hostapd does not
check the ht capabilities reported by the driver. Fix this issue making
sure ieee80211n_supported_ht_capab gets called.
