PCI: Mark Creative Labs EMU20k2 INTx masking as broken 

[ Upstream commit 2910306655a7072640021563ec9501bfa67f0cb1 ]

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.
