[ledd] prevent led crash on recirc port event (#232)

Description
Prevent ledd crash when an event on recirc port happens

Motivation and Context
A recirculation port is not a physical interface tied to a xcvr
Calling the led change event on such a port could lead to a ledd crash

How Has This Been Tested?
This change was applied to running switch with its dependency #9471
Verified that ledd runs without crashing
