Fix weird uses of num_online_cpus().
This may be OK in archs with contiguous CPU numbers and without hotplug CPUs, but it sets a terrible example. And open-coding it like drivers/scsi/hpsa.c is just weird. BTRFS has a weird comparison with num_online_cpus() too, but since BTRFS just screwed up my test machines' root partition, I'm not touching it :) Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Reported-by: Oleg Drokin <green@linuxhacker.ru>
