fix(ironic): avoid inspection failure due to missing ports

When ports are missing the code currently has an unhandled exception
instead of gracefully logging it causing inspection to fail. This
restores the intended behavior.

+Subject: [PATCH] fix: local_link_connection inspection hook does not fail on
+ missing port
+
+The code intended to not fail when a Port object was missing but to
+instead skip the handling of that node but instead there is an unhandled
+exception because the get_by_address() method throws PortNotFound
+instead of returning None when a port couldn't be found.
