hostapd: make cli treat UNKNOWN COMMAND as failing
Avoid infinite loop at 100% CPU when running hostapd_cli if CONFIG_CTRL_IFACE_MIB is not defined. _newselect(4, [3], NULL, NULL, ...) recvfrom(3, "UNKNOWN COMMAND\n", 4095, 0, NULL, NULL) = 16 sendto(3, "STA-NEXT UNKNOWN COMMAND", 24, 0, NULL, 0) = 24 Signed-off-by: Denton Gentry <denny@geekhold.com>
