[PATCH] net/intel: allow fast-free to empty cache

When freeing transmitted mbufs, there is no reason to send the freed mbufs directly to the ring if the cache is empty - only if it is zero size (in which case the cache pointer is NULL). Therefore, remove the empty check and only check for a null cache pointer. Signed-off-by: Bruce Richardson ---
