[PATCH v1 net-next 2/2] net: bridge: Remove rcu_read_lock() in br_get_link_af_size_filtered().

[Kuniyuki Iwashima <kuniyu@amazon.com>]

Since commit 5fa85a09390c ("net: core: rcu-ify rtnl af_ops"),
af_ops->get_link_af_size() is called under RCU.

Let's remove unnecessary rcu_read_lock() in br_get_link_af_size_filtered().
