    sys/kern: Make struct buf::b_dep a member of union
    
    struct buf::b_dep being a list head is too specific to UFS.
    HAMMER or other filesystems want this to be a void* pointer.
    
    It also forces HAMMER or other filesystems to define their own
    struct worklist because no such struct is defined outside of
    the UFS source which is insane in terms of a kernel structure
    for general blk i/o.
    
    Also see 71199586f.
