ecore_con: Not returning error if port is less than zero for local sockets.

ecore_con: Not returning error if port is less than zero for local sockets.

Summary:
If the socket is local, then there is no need to through error if the port is less than 0 (i.e., negetive). The behavior is same in _ecore_con_connector_eo_base_finalize funtion. So applied the same here. There is code in ecore_con_local.c to handle if port is less than zero for local sockets.
In _ecore_con_connector_eo_base_finalize function, I've added a space just so that it shows difference in phabricator and  would be easy for you to review.
