PCI: Mark Creative Labs EMU20k2 INTx masking as broken
[ Upstream commit 2910306655
]
Per user reports, the Creative Labs EMU20k2 (Sound Blaster X-Fi
Titanium Series) generates spurious interrupts when used with
vfio-pci unless DisINTx masking support is disabled.
Thus, quirk the device to mark INTx masking as broken.
