[VLAN]: Allow vlan devices registration in net namespaces.
This one is similar to what I've done for TUN - set the proper net after device allocation and clean VLANs on net exit (use the rtnl_kill_links helper finally). Plus, drop explicit init_net usage and net != &init_net checks. Signed-off-by: Pavel Emelyanov <xemul@openvz.org> Acked-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S.
