on non-partitioned table

Problem was that partitioning specific commands was accepted
for non partitioned tables and treated like
ANALYZE/CHECK/OPTIMIZE/REPAIR TABLE, after bug-20129 was fixed,
which changed the code path from mysql_alter_table to
mysql_admin_table.

Solution was to check if the table was partitioned before
trying to execute the admin command
