    ML2 BigSwitch: Don't modify parent context

    Makes a copy of the port context before changing
    it in preparation for the backend controller so
    other drivers are not affected. Also removes a
    UT that was exercising direct modification of VIF
    details in the port context, which is not allowed
    by the ML2 plugin.
