Clean up and fix VCPU hotplug and SMP save/restore.
 1. No longer hold xenbus_lock while taking down VCPUs
    in SMP suspend path. This allows block device hotplug
    to continue working and so we will not deadlock on
    paging in userspace hotplug code.
 2. Track xenbus and local-admin permitted cpumasks for
    VCPUs to bring online. So, if a local admin takes a
    CPU down, that won't surprisingly get overridden next
    time the kernel interrogates xenstore.
