[REGRESSION, bisect]vfio-pci: 'Masking broken INTx support' seen while assigning SRIOV-VF devices after commit 2170dd04316e0754("vfio-pci: Mask INTx if a device is not capabable of enabling it")

[Arjun Vynipadath <arjun@xxxxxxxxxxx>]

Hi Alexey,
Commit 2170dd0("vfio-pci: Mask INTx if a device is not capabable of enabling it") is causing 'Masking broken INTx support' messages everytime we powerup a VM with a SRIOV Virtual Function device attached. 

PCI SRIOV Virtual Functions aren't allowed to support traditional INTx Pin Interrupts as per Section 5 of the Single Root I/O Virtualization and Sharing Specification, Revision 1.0 (September 11, 2007).
Can you make us sure if this is what you intended?

Thanks,
Arjun.
