controller: Container lport install flows in MAIN chassis only.

If container lport parent_port has an additional chassis option set with
multiple chassis in some cases the container lport flows in table 0 will
be installed in all those chassis instead of the main chassis.

This patch will limit the container port flows in table 0 to only the
parent port main chassis.
