!DICT_TABLE_IS_TEMPORARY(INDEX->TABLE)

Since we don't use change buffer for spatial index, we should make sure
that those change buffer related flags are not set mistakenly with
spatial index. We will introduce a new flag called BTR_RTREE_DELETE_MARK
to replace the misused BTR_DELETE_MARK for spatial index.
