xhci: also avoid the XHCI_ZERO_64B_REGS quirk with a passthrough iommu

xhci: also avoid the XHCI_ZERO_64B_REGS quirk with a passthrough iommu

commit ecaa4902439298f6b0e29f47424a86b310a9ff4f upstream.

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.
