knfsd: when allocating per-cpu or per-node rpc thread pools, handle
the case of noncontiguous cpu or node numbers.
Tested:
Machine ARCH SMP NUMA SUNRPC nodes cpus hpni hppi pools(mode)

4 cpu Xeon SMP x86_64 y y y 1 4 31 7 4 (percpu)

* number of nodes and cpus from /sys/devices/system/
* hpni = value of highest_possible_node_id()
* hppi = value of highest_possible_processor_id()
