    Fix passing error physical network for get_mtu

Title:
  ML2 plugin does not set correct MTU for multiple provider networks

Status in neutron:
  Fix Released

Bug description:
  When using multiple provider networks type vlan the setting :
  "physical_network_mtus = net1:1500, net2:9000" is not taken only the "global_physnet_mtu=9000" 
  setting is taken.

  It seems that in /neutron/plugins/ml2/plugin.py in function
  _get_network_mtu () the call to
  type.driver.get_mtu(provider.PHYSICAL_NETWORK) is wrong.

  It should be :

  mtu = type.driver.get_mtu(s[provider.PHYSICAL_NETWORK])

  instead to read out the propper network name.

  Thanks
