Pass the full apdev to the add_ap() function instead of just ifname.
This allows us to handle also remote hosts while we can check
apdev['hostname'], apdev['port'].
This step (7) converts the cases where a local variable is used to store
apdev[#]['ifname'] before passing it as the argument to hostapd.add_ap().
