MDEV-25200 Index count mismatch due to aborted FULLTEXT INDEX

Browse Source 
- Aborting of fulltext index creation fails to remove the
index from sys indexes table. When we try to reload the
table definition, InnoDB fails with index count mismatch
error. InnoDB should remove the index from sys indexes while
rollbacking the secondary index creation.
