Michael S. Tsirkin 9e02fb9633 KVM: fix crash on irqfd deassign ...

irqfd in kvm used flush_work incorrectly: it assumed that work scheduled
previously can't run after flush_work, but since kvm uses a non-reentrant
workqueue (by means of schedule_work) we need flush_work_sync to get that
guarantee.
