[PATCH net-next 2/6] devlink: Delete useless checks of holding devlink lock

[Leon Romanovsky <leon@kernel.org>]

From: Leon Romanovsky <leonro@nvidia.com>

The snapshot API is fully protected by devlink->lock and these internal
functions are not exported directly to the code outside of the devlink.c.
This makes the checks of holding devlink lock as completely redundant.
