hostapd: Allow 'none' driver to be started without ifname

Commit 0dcc4dc4b31d48ed32940b9adb0b9fcdcab32dc3 made driver
initialization conditional on interface name being configured. This can
break hostapd-as-RADIUS-server use case where this parameter does not
really make any sense. Fix this with a special case for the none driver.
