Description

MLOG_INDEX_LOAD redo log is written during online alter table. But MLOG_INDEX_LOAD
is written for the root page even though the page is empty and for spatial index too. By fixing this, we can save some I/O for mariabackup
and even during redo log recovery. (~~MDEV-12699~~). It also saves a few bytes in the redo log.
