compat: Fix panic caused by NULL pointer derefence in rtnl_fill_ifinfo

get stats netdev ops is blindy called for older kernels (< 2.6.29) and
so assigning a NULL pointer from netdev_attach_ops causes a NULL pointer
dereference.

By default, netdev alloc provides an internal stats reference. So fill
this only if ndo_get_stats is defined.
