Remove PSMP option from ht_capab

Browse source 
This was used to fill in the "PSMP support" subfield that was defined
during P802.11n development. However, this subfield was marked reserved
in the published IEEE Std 802.11n-2009 and it is not supported by
current drivers that use hostapd for SME either. As such, there is not
much point in maintaining this field as ht_capab parameter within
hostapd either.
