Minor changes following review of the engine pull request
for this feature;
- Remove the name of the function from the error message
as it's not a debug message.
- Add the valid range to the error message, so that a
user has sufficient information to address the problem.
- Update GoDoc for the function to describe the default
port, and valid port-ranges.

This PR chnages allow user to configure VxLAN UDP
port number. By default we use 4789 port number. But this commit
will allow user to configure port number during swarm init.
VxLAN port can't be modified after swarm init.
