Merge branch 'stable/pcifront-fixes' into stable/irq.cleanup

* stable/pcifront-fixes:
  pci/xen: When free-ing MSI-X/MSI irq->desc also use generic code.
  pci/xen: Cleanup: convert int** to int[]
  pci/xen: Use xen_allocate_pirq_msi instead of xen_allocate_pirq
  xen-pcifront: Sanity check the MSI/MSI-X values
  xen-pcifront: don't use flush_scheduled_work()
