[PATCH net-next v2 3/7] devlink: devl_resource_register(): differentiate error codes

[Przemek Kitszel]

Differentiate error codes of devl_resource_register().

Replace one of -EINVAL exit paths by -EEXIST. This should aid developers
introducing new resources and registering them in the wrong order.
