netfilter: bridge: refcount fix
commit f216f082b2b37c4943f1e7c393e2786648d48f6f
([NETFILTER]: bridge netfilter: deal with martians correctly)
added a refcount leak on in_dev.
Instead of using in_dev_get(), we can use __in_dev_get_rcu(),
as netfilter hooks are running under rcu_read_lock(), as pointed
by Patrick.
