ipv6: Don't dev_hold(dev) in ip6_mc_find_dev_rcu.

Browse Source 
[ Upstream commit c577923756 ]

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 96b52e61be (ipv6: mcast: RCU conversions) ]
