[PATCH 4.19 55/63] net: dont warn in inet diag when IPV6 is disabled

[Greg Kroah-Hartman]

From: Stephen Hemminger <stephen@xxxxxxxxxxxxxxxxxx>

[ Upstream commit 1e64d7cbfdce4887008314d5b367209582223f27 ]

If IPV6 was disabled, then ss command would cause a kernel warning
because the command was attempting to dump IPV6 socket information.
The fix is to just remove the warning.

Fixes: 432490f9d455 ("net: ip, diag -- Add diag interface for raw sockets")
