    Fix Migration 50e86cb2637a and 38335592a0dc

    When the rename of quantum->neutron occurred here ee3fe4e8 it also renamed
    the the table creation from quantum_nvp_port_mapping to
    neutron_nvp_port_mapping. This went undetected for a long time because
    when neutron-server starts up it pushes down the scheme for tables that
    are not there so the table would be created.

    Because of this the following migration 50e86cb2637a called
    op.rename_table('neutron_nvp_port_mapping', 'neutron_nsx_port_mappings')
    though the table name being used was quantum_nvp_port_mapping. Because of this
    the quantum_id->nvp_id mapping was never migrated over to the new table and
    you would be left with a quantum_nvp_port_mapping table hanging around.

    In addition, the downgrade would rename the table to neutron_nvp_port_mapping
    instead of quantum_nvp_port_mapping. This patch addresses this issues.
