[NET]: Wider use of for_each_*cpu()
In 'net' change the explicit use of for-loops and NR_CPUS into the general for_each_cpu() or for_each_online_cpu() constructs, as appropriate. This widens the scope of potential future optimizations of the general constructs, as well as takes advantage of the existing optimizations of first_cpu() and next_cpu(), which is advantageous when the true CPU count is much smaller than NR_CPUS.
