devstack/lib/neutron_plugins/ml2
Akihiro Motoki 130c90ed0b Do not create an unnecessary file "ml2"
Previously when running devstack with Neutron ML2 plugin,
an unnecessary file "ml2" is created in devstack directory.
It is because when the first argument is not defined the second
argument becomes the first one.

This change moves the first "options" argument of populate_ml2_config
to the last and checks the given options has a value before adding
them to a file.
