To make get/set netlink VF_PORT truly symmetrical, we need to keep track
of what items are set and only return those items on get. Previously, the
driver wasn't differentiating between a set of attr with a NULL string,
for example, and not setting the attr at all. We only want to return
the NULL string if the attr was actually set with a NULL string. Otherwise,
don't return the attr.
