fix ndb_cache_multi2

util thread wasn't behaving correctly after 241 error due to get_table_statistics
not properly returning an error code


sql/ha_ndbcluster.cc:
  correctly call ndb_get_table_statistics in get_commitcount (don't report error)
  
  but also return an error code from get_table_statistics so that util thread
  gets error code
