xen: credit2: make the cpu to runqueue map per-cpu

Instead of keeping an NR_CPUS big array of int-s,
directly inside csched2_private, use a per-cpu
variable.

That's especially beneficial (in terms of saved
memory) when there are more instance of Credit2 (in
different cpupools), and also helps fitting
csched2_private itself into CPU caches.
