The cache pickup does a check for duplicates for some time now.
However, the pickup in nl_cache_refill() explicitely clears the
cache, so the pickup doesn't need to actually do the dupe check,
as uniqueness is already guaranteed be Netlink subsystem.
And avoiding the dup check is beneficitial for performance
reasons, as the current algorithm is O(n^2).
