ipv6: Use ipv6_get_dsfield() instead of ipv6_tclass().
Commit 7a3198a8 ("ipv6: helper function to get tclass") introduced
ipv6_tclass(), but similar function is already available as
ipv6_get_dsfield().
We might be able to call ipv6_tclass() from ipv6_get_dsfield(),
but it is confusing to have two versions.
