[PATCH] WPS: Can't clear WPS IE with madwifi driver

[Masashi Honma]

Hello.

On WPS init/deinit process, the hostapd clears it's own WPS IE
with 0 length WPS IE. But it fails. Because the parameter to
ioctl is too short. Then hostapd prints a below message.

ioctl[IEEE80211_IOCTL_SET_APPIEBUF]: Invalid argument

Below patch will solve this.

diff --git a/hostapd/driver_madwifi.c b/hostapd/driver_madwifi.c
