    sbin/hammer: Split alloc_bigblock() into two functions [2/2]
    
    This function is currently only used by zone-3, but it's actually
    only usable by zone-3 from the way it's implemented, so rename it
    to alloc_undo_bigblock() and get rid of zone argument.
    
    The way blockmap offsets (in root volume) get updated for zone-3
    differs from other zones like 8/9/10/11, and this function which
    doesn't update blockmap offsets on allocation only works against
    zone-3.
