net: wrap the wireless pointers in struct net_device in an ifdef
Most protocol-specific pointers in struct net_device are under
a respective ifdef. Wireless is the notable exception. Since
there's a sizable number of custom-built kernels for datacenter
workloads which don't build wireless it seems reasonable to
ifdefy those pointers as well.
While at it move IPv4 and IPv6 pointers up, those are special
for obvious reasons.
