Incorrect usage of sqlalchemy type Integer

[Ann Taraday]

In migration folsom_initial in cisco_upgrade function table nexusport_bindings create column vlan_id with incorrect type Integer(255). It causes the following exception:
  File "/opt/stack/neutron/neutron/db/migration/alembic_migrations/versions/folsom_initial.py", line 87, in upgrade
    upgrade_cisco()
  File "/opt/stack/neutron/neutron/db/migration/alembic_migrations/versions/folsom_initial.py", line 455, in upgrade_cisco
    sa.Column('vlan_id', sa.Integer(255)),
TypeError: object() takes no parameters
