Revert "net: maintain namespace isolation between vlan and real device"

Browse Source 
This reverts commit 8a83a00b07.

It causes regressions for S390 devices, because it does an
unconditional DST drop on SKBs for vlans and the QETH device
needs the neighbour entry hung off the DST for certain things
on transmit.

Arnd can't remember exactly why he even needed this change.
