[PATCH v2 net-next 1/8] net: fib_rules: Don't check net in rule_exists() and rule_find().

[Kuniyuki Iwashima <kuniyu@amazon.com>]

fib_nl_newrule() / fib_nl_delrule() looks up struct fib_rules_ops
in sock_net(skb->sk) and calls rule_exists() / rule_find() respectively.

fib_nl_newrule() creates a new rule and links it to the found ops, so
struct fib_rule never belongs to a different netns's ops->rules_list.

Let's remove redundant netns check in rule_exists() and rule_find().
