BUG#19914 SELECT COUNT(*) sometimes returns MAX_INT on cluster tables

post-review fixes as indicated by Serg.

manual testing of error cases done in 5.0 due to support for DBUG_EXECUTE_IF
to insert errors.
Unable to write test case for mysql-test until 5.1 due to support for setting
debug options at runtime.
