[PATCH net-next] selftests: mlxsw: rtnetlink: Use devlink_reload() API

[Petr Machata]

From: Amit Cohen <amcohen@nvidia.com>

The test runs "devlink reload" explicitly. Instead, it is better to use
devlink_reload() which waits for udev events to be processed. Do not sleep
after reload, as devlink_reload() blocks until all the netdevs are renamed.
