packet: less dev_put() calls - packet_sendmsg_spkt() can use dev_get_by_name_rcu() to avoid touching device refcount. - packet_getname_spkt() & packet_getname() can use dev_get_by_index_rcu() to avoid touching device refcount too. tpacket_snd() & packet_snd() can not use RCU yet because they can sleep when allocating skb.
