Heiner Kallweit f7368a5502 PCI: Use IRQF_ONESHOT if pci_request_irq() called with no handler ...

If we have a threaded interrupt with the handler being NULL, then
request_threaded_irq() -> __setup_irq() will complain and bail out if the
IRQF_ONESHOT flag isn't set.  Therefore check for the handler being NULL
and set IRQF_ONESHOT in this case.

This change is needed to migrate the mei_me driver to
pci_alloc_irq_vectors() and pci_request_irq().
