inet: remove now unused flag DST_NOPEER

Commit e688a60 ("net: introduce DST_NOPEER dst flag") introduced DST_NOPEER because because of crashes in ipv6_select_ident called from udp6_ufo_fragment. Since commit 916e4cf ("ipv6: reuse ip6_frag_id from ip6_ufo_append_data") we don't call ipv6_select_ident any more from ip6_ufo_append_data, thus this flag lost its purpose and can be removed.
