Subject: [PATCH iproute2] ss: Fix case when UDP is printed as ipproto-xxx

From: Vadim Kochan <vadim4j@...il.com>

When 'ss' prints UDP sockets info together with RAW sockets
e.g.:

    $ ss -a

then UDP sockets are resolved as "ipproto-xxx".

It was caused that dg_proto was set after printing UDP
socket info from netlink. So fixed issue by moving
setting dg_proto before printing info from Netlink.
