rhashtable: remove insecure_max_entries param
no users in the tree, insecure_max_entries is always set to ht->p.max_size * 2 in rhtashtable_init(). Replace only spot that uses it with a ht->p.max_size check. Signed-off-by: Florian Westphal <fw@strlen.de> Signed-off-by: David S. Miller <davem@davemloft.net>
