    Remove 11.x ABI compat for kernel dump ioctls
    
    This code was marked gone_in(13), so its time has passed.
    
    The only consumer of this interface is dumpon(8). We do not maintain
    strict backwards compatibility for this utility because a) it
    can't/shouldn't be used from a jail or chroot and b) it is highly
    specific interface unique to FreeBSD. The host's (presumably more
    up-to-date) copy of dumpon(8) should be used to configure kernel dump
    devices.
