iommu/vt-d: Remove control over Execute-Requested requests
The VT-d specification has removed architectural support of the requests
with pasid with a value of 1 for Execute-Requested (ER). And the NXE bit
in the pasid table entry and XD bit in the first-stage paging Entries are
deprecated accordingly.
Remove the programming of these bits to make it consistent with the spec.
