Two cases in ha_partition::extra() was missing
(HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH)
which only is currently used by NDB (which not uses ha_partition)


mysql-test/r/partition.result:
  Added result for test of Bug #30484
mysql-test/t/partition.test:
  Added test for Bug #30484
sql/ha_partition.cc:
  Added HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH
  in ha_partition::extra to do nothing
  (Only currently used in NDB, which is not dependent of ha_partition)
