Ruimei Yan fc967aad40 hw/usb: hcd-xhci-pci: Fix spec violation of IP flag for MSI/MSI-X 
Per xHCI spec v1.2 chapter 4.17.5 page 296:

  If MSI or MSI-X interrupts are enabled, Interrupt Pending (IP)
  shall be cleared automatically when the PCI dword write generated
  by the interrupt assertion is complete.

Currently QEMU does not clear the IP flag in the MSI / MSI-X mode.
This causes subsequent spurious interrupt to be delivered to guests.
To solve this, we change the xhci intr_raise() hook routine to have
a bool return value that is passed to its caller (the xhci core),
with true indicating that IP should be self-cleared.

Fixes: 62c6ae04cf ("xhci: Initial xHCI implementation")
Fixes: 4c47f80063 ("xhci: add msix support")
