The return value of the get link function call was not checked, and
could return a negative value indicating a failure. This meant the
link_status of the link being checked is invalid, because the link was
not filled with data. The return value is now checked, and if the return
value is not 0 for success, the loop continues with the next port.
To avoid confusion between variable names, the existing retval variable
is renamed to link_status, to better represent its use.
