    This patch fixes the following defects/bugs.
    1. If BKA[H] algorithm was used to join a table for which the optimizer
    had decided to employ a rowid filter the filter actually was not built.
    2. The patch for the bug MDEV-21356 that added the code canceling pushing
    rowid filter into an engine for the table joined with employment of
    BKA[H] and MRR was not quite correct for Innodb engine because this
    cancellation was done after InnoDB code had already bound the the pushed
    filter to internal InnoDB structures.
