xhci: also avoid the XHCI_ZERO_64B_REGS quirk with a passthrough iommu
Previously the quirk was skipped when no iommu was present. The same
rationale for skipping the quirk also applies in the iommu.passthrough=1
case.
Skip applying the XHCI_ZERO_64B_REGS quirk if the device's iommu domain is
passthrough.
