net: move net_device priv_flags out from UAPI

Browse source 
These are private to userspace, and they're unstable
anyway and can be shuffled at will (see 080e4130b1)
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
