VMware: Remove OVS from the networking section of the vSphere driver doc

[Dan Florea]

There was a change made that specified OVS can be configured with the vSphere driver. The change is the following:

https://github.com/openstack/openstack-manuals/commit/40ec040797b98444d6a1d7eb0bd614f7bd9338c2
"The OpenStack Networking Service. If you use OVS as the l2 agent, create a port group with the same name as the DEFAULT.neutron_ovs_bridge value in the nova.conf file. Otherwise, create a port group with the same name as the vmware.integration_bridge value in the nova.conf file. In both cases, the default value is br-int."

This is actually incorrect since with the OVS configuration above, all VMs would be placed in a single port group and any Neutron configuration would not function properly. The line above about OVS configuration should be removed.
