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 :)
