Resolves issue with vmware_vswitch module for v2.0

Browse source 
When this module was written back in May 2015 we were using 1.9.x. Being lazy I added to param the objects that the other functions would need. What I have noticed is in 2.0 exit_json is trying to jsonify those complex objects and failing.

Playbook
```yaml
   - name: Add a temporary vSwitch
      local_action:
        module: vmware_vswitch
        hostname: "{{ inventory_hostname }}"
        username: "{{ esxi_username }}"
        password: "{{ site_passwd }}"
        switch_name: temp_vswitch
        nic_name: "{{ vss_vmnic }}"
        mtu: 1500
```

Module Testing
```bash
