There are several cases of an invalid port data access that causes the
printing of all the valid ports, for example, when the user asks to
receive a port information of an invalid port.
Wrongly, the port with id 0 is printed in all the above described
cases, regardless of its validity.
Print port 0 only if it is valid as done for the rest of the ports.
