Subject: [patch net] devlink: fix port dump cmd type

From: Jiri Pirko <jiri@...dia.com>

Unlike other commands, due to a c&p error, port dump fills-up cmd with
wrong value, different from port-get request cmd, port-get doit reply
and port notification.

Fix it by filling cmd with value DEVLINK_CMD_PORT_NEW.

Skimmed through devlink userspace implementations, none of them cares
about this cmd value. Only ynl, for which, this is actually a fix, as it
expects doit and dumpit ops rsp_value to be the same.

Omit the fixes tag, even thought this is fix, better to target this for
next release.
