commit c0b7f7d7e0ad44f35745c01964b3fa2833e298cb upstream.

In the blamed commit, the call to the function
switchdev_bridge_port_offload was passing the wrong argument for
atomic_nb. It was ocelot_netdevice_nb instead of ocelot_swtchdev_nb.
This patch fixes this issue.

Fixes: 4e51bf44a03af6 ("net: bridge: move the switchdev object replay helpers to "push" mode")
