Alexey Dobriyan be77e59307 net: fix tunnels in netns after ndo_ changes 
dev_net_set() should be the very first thing after alloc_netdev().

"ndo_" changes turned simple assignment (which is OK to do before netns
assignment) into quite non-trivial operation (which is not OK, init_net was
used). This leads to incomplete initialisation of tunnel device in netns.

BUG: unable to handle kernel NULL pointer dereference at 00000004
