MDEV-23722 InnoDB: Assertion: result != FTS_INVALID in fts_trx_row_get_new_state

Browse Source 
Marking of deletion of row in fts index happens twice in
self-referential foreign key relation. So while performing
referential checks of foreign key, InnoDB can avoid updating
of fts index if the foreign key has self-referential relationship.
