Way to complex for my taste :)

How about

hostapd_enable="YES"
hostapd_interfaces="wlan0 wlan1 .." # defaults to empty

and then

if [ -n $hostapd_interfaces ]; then
	for interface in $interface; do
		pidfile=/var/run/hostapd/$interface.pid
		conffile=/etc/hostapd-$interface.conf
		..
	done
else
	pidfile=/var/run/hostapd.pid
	conffile=/etc/hostapd.conf
fi
