Instead of calling into kvm_timer_[un]schedule from the main kvm blocking path, test if the VCPU is on the wait queue from the load/put path and perform the background timer setup/cancel in this path. This has the distinct advantage that we no longer race between load/put and schedule/unschedule and programming and canceling of the bg_timer always happens when the timer state is not loaded. Note that we must now remove the checks in kvm_timer_blocking that do not schedule a background timer if one of the timers can fire, because we no longer have a guarantee that kvm_vcpu_check_block() will be called before kvm_timer_blocking.
