pci: Fix clearing IRQs on reset
irq_state is cleared before calling pci_device_deassert_intx, but the
latter misbehaves if the former isn't accurate. In this case, any raised
IRQs are not cleared, which hits an assertion in pcibus_reset:
qemu-system-x86_64: hw/pci/pci.c:250: pcibus_reset: Assertion
`bus->irq_count[i] == 0' failed.
pci_device_deassert_intx should clear irq_state anyways, so add
an assert.
This fixes migration with usb2 + usb-tablet.
