net-sysfs: call dev_hold if kobject_init_and_add success
[ Upstream commit a3e23f719f5c4a38ffb3d30c8d7632a4ed8ccd9e ]
In netdev_queue_add_kobject and rx_queue_add_kobject,
if sysfs_create_group failed, kobject_put will call
netdev_queue_release to decrease dev refcont, however
dev_hold has not be called. So we will see this while
unregistering dev:
unregister_netdevice: waiting for bcsh0 to become free. Usage count = -1
