The BSS supplicant command returns a 0 len reply when failing to pasrse some information for a BSS. This patch make the function wpa_supplicant_ctrl_iface_bss() return -1 on such cases instead of 0 and therefore the BSS command will return FAIL. This is important since when using udp control interfaces sending a 0 len reply does not send a reply at all and the control interface can wait forever (or until a timeout is reached) for a reply.
