virtio_mmio: disable IRQ wake before free_irq
When the DT node has "wakeup-source", vm_find_vqs() calls
enable_irq_wake() on the shared IRQ, but vm_del_vqs() freed that IRQ
without a matching disable_irq_wake(). That leaves a wake reference
behind and can warn on later free_irq()/request_irq() cycles.
Record whether enable_irq_wake() succeeded, and disable it in
vm_del_vqs() before free_irq().
Fixes: 02213273f72a ("virtio_mmio: add support to set IRQ of a virtio device as wakeup source")
