netfilter: xt_qtaguid: work around devices that reset their stats
Most net devs will not reset their stats when just going down/up,
unless a NETDEV_UNREGISTER was notified.
But some devs will not send out a NETDEV_UNREGISTER but still
reset their stats just before a NETDEV_UP.
Now we just track the dev stats during NETDEV_DOWN... just in case.
Then on NETDEV_UP we check the stats: if the device didn't do a
NETDEV_UNREGISTER and a prior NETDEV_DOWN captured stats, then we treat
it as an UNREGISTER and save the totals from the stashed values.
Added extra netdev event debugging.
