====================
devlink: warn about existing entities during reload-reinit

Recently there has been a couple of attempts from drivers to block
devlink reload in certain situations. Turned out, the drivers do not
properly tear down ports and related netdevs during reload.

To address this, add couple of checks to be done during devlink reload
reinit action. Also, extend documentation to be more explicit.
