    sys/dev/disk/dm: Separate dm_dev_rem_dev() from dm_dev_rem()
    
    dm_dev_rem() should be separated into two functions where
    one takes *dmv and the other takes name,uuid,minor for args.
    
    If a caller has a pointer to dm device, then it basically
    never use the rest. If not the caller may use all the rest.
    
    dm_dev_rem() currently taking all four args makes it more
    complicated than it should. Also this is closer to the
    original NetBSD implementation.
