Cisco: Nexus plugin should not be invoked for port update if it is not configured

[Abhishek Raut]

The Nexus switch is being invoked to update port when it is not configured. Only the N1KV plugin should be invoked.

Affects only stable/icehouse. Nexus plugin is removed in Juno.

    Cisco: update_port should only invoke n1kv and not nexus plugin

    Update port method should not invoke the nexus plugin when it is
    not configured with n1kv plugin. This patch adds a condition to the
    update_port method making sure that nexus plugin is invoked only
    when it is configured in cisco_plugins.ini file. This bug is only
    targeted for the stable/icehouse release since the nexus monolithic
    plugin code has been removed from Juno release onwards.
