Subject: [PATCH net-next] rocker: gaurd against NULL rocker_port when removing ports

From: Scott Feldman <sfeldma@...il.com>

The ports array is filled in as ports are probed, but if probing doesn't
finish, we need to stop only those ports that where probed successfully.
Check the ports array for NULL to skip un-probed ports when stopping.
