MDEV-21610 Different query results from 10.4.11 to 10.4.12
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.
