net: ehea: fix possible memory leak in ehea_register_port()
[ Upstream commit 0e7ce23a917a9cc83ca3c779fbba836bca3bcf1e ]
If of_device_register() returns error, the of node and the
name allocated in dev_set_name() is leaked, call put_device()
to give up the reference that was set in device_initialize(),
so that of node is put in logical_port_release() and the name
is freed in kobject_cleanup().
