dropbear: ensure the interface has an ip-address
Use network_get_ipaddrs_all to get all ip-addresses of an interface. If the function fails, the interface does not exists or has not any suiteable ip addresses assigned. Use the returned ip-address(es) to construct the dropbear listen address. Signed-off-by: Mathias Kresin <openwrt@kresin.me> SVN-Revision: 42857
