Subject: devlink: Simplify devlink_pernet_pre_exit call
Patch-mainline: v5.15-rc1
Git-commit: cbf6ab672eb425ac1cd7f8c7c4066f3bb0a78e50
References: jsc#SLE-19253

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.
