FILS: Check req_ies for NULL pointer in hostapd_notif_assoc()

Browse source 
Add checking for NULL req_ies when FILS processing a driver ASSOC event
in hostapd_notif_assoc(). This was already done in number of old code
paths, but the newer FILS path did not handle this. Though, it is
unlikely that this code path would be reachable in practice since this
is all within sta->auth_alg == WLAN_AUTH_FILS_* check.
