Add hot cpu notifier to reset the request virtqueue affinity
when doing cpu hotplug.

You need to be careful to get_online_cpus() and put_online_cpus() here,
so CPUs can't go up and down in the middle of operations.

In particular, get_online_cpus()/put_online_cpus() around calls to
virtscsi_set_affinity() (except within notifiers).

Yes, I'll take care of this, thank you.

I squashed patch 1 (plus changes to get/put_online_cpus) in my
multiqueue series, and applied this one as a separate patch.
