devlink: Decouple rate storage from associated devlink object

Browse source

Devlink rate leafs and nodes were stored in their respective devlink
objects pointed to by devlink_rate->devlink.

This patch removes that association by introducing the concept of
'rate node devlink', which is where all rates that could link to each
other are stored. For now this is the same as devlink_rate->devlink.

After this patch, the devlink rates stored in this devlink instance
could potentially be from multiple other devlink instances. So all rate
node manipulation code was updated to:
- correctly compare the actual devlink object during iteration.
- maybe acquire additional locks (noop for now).
