sit: no longer rely on RTNL in ipip6_fill_info()

Browse source

Now that SIT parameters and 6RD parameters are RCU-protected,
and fwmark/encap are annotated with READ_ONCE()/WRITE_ONCE(),
ipip6_fill_info() no longer requires RTNL to be held.

Wrap the attribute serialization in rcu_read_lock() and rcu_read_unlock().
