On guest entry, vcpu->cpu and vcpu->arch.thread_cpu are set after
disabling host irqs. On guest exit there is a window whre tick time
accounting briefly enables irqs before these fields are cleared.

Move them up to ensure they are cleared before host irqs are run.
This is possibly not a problem, but is more symmetric and makes the
fields less surprising.
