At a glance of the code, rswitch_ether_port_deinit_one appears to check various pointers before doing anything and skips any real work if those pointers aren't initialized. Either way, this seems like a good cleanup, though it might not warrant a fixes or net target if there is no user visible bug associated with it.

In rswitch_ether_port_init_all(), only enabled ports are initialized. Then, rswitch_ether_port_deinit_all() shall also only deinitialize enabled ports.
