devlink: Simplify devlink_pernet_pre_exit call

Browse source 
The devlink_pernet_pre_exit() will be called if net namespace exits.

That routine is relevant for devlink instances that were assigned to
that namespaces first. This assignment is possible only with the following
command: "devlink reload DEV netns ...", which already checks reload support.
