    rctl(4): support throttling resource usage to 0

    For rate-based resources that support throttling (e.g.
    readiops/writeips), this fixes a divide-by-zero panic when rctl(8)
    passes 0 as the throttle value.  For these resources, treat
    zero-throttle requests as requests to suspend forward progress as long
    as possible using the duration specified in
    kern.racct.rctl.throttle_max.
