    md: be more careful setting MD_CHANGE_CLEAN · 676e42d8

    When MD_CHANGE_CLEAN is set we might block in md_write_start.
    So we should only set it when fairly sure that something will clear
    it.
    
    There are two places where it is set so as to encourage a metadata
    update to record the progress of resync/recovery.  This should only
    be done if the internal metadata update mechanisms are in use, which
    can be tested by by inspecting '->persistent'.
