After DISCARD TABLESPACE, the tablespace of a table will no longer exist, and dict_get_and_save_data_dir_path() would invoke dict_get_first_path() to read an entry from SYS_DATAFILES. For some reason, DISCARD TABLESPACE would not to remove the entry from there. dict_get_and_save_data_dir_path(): If the tablespace has been discarded, do not bother trying to read the name. Side note: The tables SYS_TABLESPACES and SYS_DATAFILES are redundant and subject to removal in MDEV-22343.
