    sys/sys: Fix IOCPARM_MAX
    
    Fix the previous commit brought in from from FreeBSD at GitHub
    598dc07f1ee077b425c2f447aeb3dfb632a1f2a3.
    
    The max possible size for ioctl structure is ((1<<13)-1).
    (1<<13) bit overlaps IOC_VOID, so it gets cut by _IOC().
    Also see L672 of sys/kern/sys_generic.c.
