net: move net_device priv_flags out from UAPI

These are private to userspace, and they're unstable
anyway and can be shuffled at will (see 080e4130b1fb)
so any userspace application relying on them is on crack.

Test compiled with allyesconfig.

mcgrof@drvbp1 /pub/mem/mcgrof/net-next (git::master)$ make allyesconfig
mcgrof@drvbp1 /pub/mem/mcgrof/net-next (git::master)$ time make -j 20
