    The tree logging code was trying to separate tree log allocations
    from normal metadata allocations to improve writeback patterns during
    an fsync.
    
    But, the code was not effective and ended up just mixing tree log
    blocks with regular metadata.  That seems to be working fairly well,
    so the last_log_alloc code can be removed.
