Subject: [PATCH net-next v3 05/11] devlink: use -ENOSPC to indicate no more room for snapshots

The devlink_region_snapshot_create function returns -ENOMEM when the
maximum number of snapshots has been reached. This is confusing because
it is not an issue of being out of memory. Change this to use -ENOSPC
instead.
