hw/usb: hcd-xhci-pci: Raise MSI/MSI-X interrupts only when told to
At present MSI / MSI-X interrupts are triggered regardless of the
irq level. We should have checked the level to determine whether
the interrupt needs to be delivered.
The level check logic was present in early versions of the xhci
model, but got dropped later by a rework of interrupt handling
under commit 4c4abe7cc903 ("xhci: rework interrupt handling").
Fixes: 4c4abe7cc903 ("xhci: rework interrupt handling")
