From: Leon Romanovsky <leonro@xxxxxxxxxx>
This change prevents from users to access device before devlink is
fully configured. Indirectly this change fixes the commit mentioned
below where devlink_unregister() was prematurely removed.
Fixes: db4278c55fa5 ("devlink: Make devlink_register to be void")
