smp: Improve locality in smp_call_function_any()
smp_call_function_any() tries to make a local call as it's the cheapest
option, or switches to a CPU in the same node. If it's not possible, the
algorithm gives up and searches for any CPU, in a numerical order.
Instead, it can search for the best CPU based on NUMA locality, including
the 2nd nearest hop (a set of equidistant nodes), and higher.
sched_numa_find_nth_cpu() does exactly that, and also helps to drop most
of the housekeeping code.
