[Qemu-stable] [PULL 12/13] pci: deassert intx when pci device unrealize

[Michael S. Tsirkin]

From: "Herongguang (Stephen)" <address@hidden>

If a pci device is not reset by VM (by writing into config space)
and unplugged by VM, after that when VM reboots, qemu may assert:
pcibus_reset: Assertion `bus->irq_count[i] == 0' failed
