A recent commit added taking the netdev instance lock
in netdev_nl_bind_rx_doit(), but didn't remove it in
net_devmem_unbind_dmabuf() which it calls from an error path.
Always expect the callers of net_devmem_unbind_dmabuf() to
hold the lock. This is consistent with net_devmem_bind_dmabuf().
(Not so) coincidentally this also protects mp_param with the instance
lock, which the rest of this series needs.
Fixes: 1d22d3060b ("net: drop rtnl_lock for queue_mgmt operations")
