net: Report dev->promiscuity in netlink reports.
The standard ways of probing a device's promiscuity
(ifi_flags, for instance) does not report the actual
state of the device. This patch adds dev->promiscuity
to the netlink netdevice report so that users can know
for certain if the device is acting PROMISC or not.
