Don't differentiate between TCP and SSL ports for OpenFlow and OVSDB.

The OVS code has always made a distinction between the unencrypted (TCP)
and SSL port numbers for the OpenFlow and OVSDB protocols.  The default
port numbers for both protocols has changed, and there continues to be
no distinction between the unencrypted and SSL versions.  This
commit removes the distinction in port numbers.  A future patch will
recognize the change in default port number.
