ipv6: Don't dev_hold(dev) in ip6_mc_find_dev_rcu.
[ Upstream commit c577923756b7fe9071f28a76b66b83b306d1d001 ]
ip6_mc_find_dev_rcu() is called with rcu_read_lock(), so don't
need to dev_hold().
With dev_hold(), not corresponding dev_put(), will lead to leak.
[ bug introduced in 96b52e61be1 (ipv6: mcast: RCU conversions) ]
