MDEV-12279: rocksdb.tbl_opt_data_index_dir fails, wrong error code

Change the returned error code to be ER_CANT_CREATE_TABLE.
Emit the warning text ourselves.

(When a query produces both an error and a warning, command-line client
with default settings will not provide any indication that the warning
is present, unfortunately. Need \W)
