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.
