Commit 3a38429 ("spapr: Add a "no HPT" encoding to HTAB migration stream")
allows to migrate an empty HPT, but doesn't mark correctly the
end of the migration stream.
The end condition (value returned by htab_save_iterate() and
htab_save_complete()) should be 1, whereas in 3a38429 they
return 0.
The problem can be reproduced with QEMU monitor command "savevm":
the command never stops and the disk image grows without limit.
