Subject: [patch net-next v3/repost 1/3] net: devlink: fix unlocked vs locked functions descriptions

From: Jiri Pirko <jiri@...dia.com>

To be unified with the rest of the code, the unlocked version (devl_*)
of function should have the same description in documentation as the
locked one. Add the missing documentation. Also, add "Context"
annotation for the locked versions where it is missing.
