    MDEV-28443: MDEV-15250 causes latch order violation · 0f717d03

    Problem:
    =======
    Index page latches must be acquired before undo page latches.
    In trx_t::apply_log(), InnoDB acquired undo log page latch
    before an index page latch.
    
    Solution:
    ========
    In trx_t::apply_log(), InnoDB should copy the undo log
    record and release the undo log block before applying
    it on online indexes.
