[0/2] Add iterator for an entity's data links

Message

There are a bunch of places in the kernel where code iterates over an entity's
links to perform some action. Those almost invariably have the implicit
assumption that those links are data links, which might not be true following
the introduction of ancillary links. Add a dedicated iterator that skips any
non data links for use instead, which will allow that assumption to hold true.
