Update git submodules

* Update docs/submodules/sfc from branch 'master'
  - Change the test result comparison in 'test_odl_utils.py' #L103

    When 'get_active_rsps_on_ports' is executed, it returns a list of
    unordered dictionaries, sorting the result to verify the return
    value would fix the test assertion.
