Add permission check for MERGE/SPLIT partition operations

Currently, we check only owner permission for the parent table before
MERGE/SPLIT partition operations. This leads to a security hole when users
can get access to the data of partitions without permission. This commit
fixes this problem by requiring owner permission on all the partitions
involved.
