dpif_id() is often used in error messages, e.g. "dp%u: screwed up". But soon we will be generalizing the concept of a datapath, so it is better to have a function that returns a full name, e.g. "%s: screwed up". Accordingly, this commit replaces dpif_id() by a new function dpif_name() that does so.
