Lu Baolu 06f4b8d09d iommu/vt-d: Remove unnecessary SVA data accesses in page fault path
The existing I/O page fault handling code accesses the per-PASID SVA data
structures. This is unnecessary and makes the fault handling code only
suitable for SVA scenarios. This removes the SVA data accesses from the
I/O page fault reporting and responding code, so that the fault handling
code could be generic.
