Bug #11766851 QUERYING I_S.PARTITIONS CHANGES THE CARDINALITY OF THE
PARTITIONS.
ANALYSIS
--------
Whenever we query I_S.partitions,
ha_partition::get_dynamic_partition_info()
is called which resets the cardinality
according to the number of rows in last
partition.
Fix
---
When we call get_dynamic_partition_info()
avoid passing the flag HA_STATUS_CONST
to info() since HA_STATUS_CONST should
ideally not be called for per partition.
