Changing the tablespace of a table using an inplace alter table fails to
update NDB dictionary with the new tablespace name and tablespace id.
Even if an attempt to update the NDB dictionary was made, it would not
properly move over data to the new tablespace.

Fix by not allowing TABLESPACE to be changed by inplace alter table
until NDB supports changing tablespace online.

Restrict both cases:
1) Assigning a table (which does not already has one) to a tablespace
2) Changing the tablespace of a table

Add printout of tablespace id and name to make them visible in
for example ndb_desc.
