Fix hostapd wmm_enabled setup on config reload path 

If there is no explicit wmm_enabled parameter in the configuration
(i.e., conf->wmm_enabled == -1), the configuration reload path needs to
initialize conf->wmm_enabled based on iconf->ieee80211n in
hostapd_reload_bss() similarly to what is done in the initial startup
case in hostapd_setup_bss().

This fixes issues with RSN capabilities being set incorrectly when WMM
is supposed to get enabled and unexpectedly enabling WMM when it is not
supposed to be enabled (HT disabled). Either of these issues could show
up when asking hostapd to reload the configuration file (and when that
file does not set wmm_enabled explicitly).
