spapr_tce_table_finalize() can SEGV if the object was not previously
realized. In particular this can be triggered by running
qemu-system-ppc -device spapr-tce-table,?
The basic problem is that we have mismatched initialization versus
finalization: spapr_tce_table_finalize() is attempting to undo things that
are done in spapr_tce_table_realize(), not an instance_init function.
Therefore, replace spapr_tce_table_finalize() with
spapr_tce_table_unrealize().
