create_table in downgrade does not match table's content before migration

[Ann Taraday]

create_table in downgrade in migration 2a6d0b51f4bb_cisco_plugin_cleanup does not match table's content created by migration folsom_initial, because of this there is a problem with downgrade.

File "/opt/stack/neutron/neutron/db/migration/alembic_migrations/versions/2a6d0b51f4bb_cisco_plugin_cleanup.py", line 87, in downgrade
    sa.PrimaryKeyConstraint(u'id')
