Joerg Roedel 11d9bb923f iommu/amd: Don't clear DTE flags when modifying it 
commit cbf3ccd09d upstream.

During device assignment/deassignment the flags in the DTE
get lost, which might cause spurious faults, for example
when the device tries to access the system management range.
Fix this by not clearing the flags with the rest of the DTE.
