hostapd: Do not terminate process on dynamic interface add failure

Browse Source 
Limit the calls to eloop_terminate() to happen only for the
initialization failure from the interfaces that we specified on the
command line. This allows hostapd process to continue operating even if
a dynamically added interface fails to start up. This allows the upper
layer software to fix a configuration error and retry.
