All of the i40e (XL710/X710) 10/20/40GbE NICs lack support for indicating
INTx is asserted via the interrupt bit in the PCI status register.  The
DisINTx bit in the command register is functional, causing these devices to
be incorrectly detected as supporting INTx masking.  Quirk them to properly
indicate no INTx masking support.
