[PATCH] hostapd: fix interfaces.iface initialization

[Guy Eilam]

Set all the interfaces.iface pointers to NULL after
the allocation of that memory block for cases those
pointers are accessed during each of the interfaces
initialization process (hostapd_interface_init()).
One example for such case is during WPS initialization when
the code tries to fetch the uuid from each of the interfaces.
