net: xfrm: revert to lower xfrm dst gc limit
revert c386578f1cdb4dac230395 ("xfrm: Let the flowcache handle its size by default."). Once we remove flow cache, we don't have a flow cache limit anymore. We must not allow (virtually) unlimited allocations of xfrm dst entries. Revert back to the old xfrm dst gc limits. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
