AP MLD: Allow new link to be added through control interface

AP MLD link is added with the same interface name but current control
interface command "ADD" does not consider tjat AP MLD case yet.

Modify the logic here to support adding a new AP MLD link from the "ADD"
command, too, by adding a new hostapd_iface structure instead of just a
new BSS into the existing structure.
