Janusz Dziedzic 8b8a1864ff tests: Pass full apdev to add_ap() function (1)
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 (1) converts the cases where apdev[#]['ifname'] was used as
the argument to hostapd.add_ap().
