enic: bug fix: make the set/get netlink VF_PORT support symmetrical

From: Scott Feldman <[email protected]>

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.
