wifi-scripts: fix race in wireless interface creation

When wdev interfaces and hostapd interfaces are mixed, race conditions
can occur. Sometimes all interfaces are started correctly, sometimes only
the wdev interface and some of the hostapd interfaces, and sometimes only
the wdev interface.

Fix this by creating the wdev interfaces first, before processing
wpa_supplicant or hostapd interfaces.
