[PATCH] wpa_supplicant: Fix updating GO beacons on WFD subelements change

[Ilan Peer]

From: Andrei Otcheretianski <andrei.otcheretianski at intel.com>

When WFD Subelements are set, the ie in the
beacons of already existing groups are not updated.
This patch fixes this issue by setting beacon_update to be 1.
