iommu/vt-d: Use logical OR operator for privilege mode check

Browse Source 
Replace bitwise OR (|) with logical OR (||) in the privilege mode
validation check. While both operators produce the same result for
boolean values (0 or 1), using logical OR is semantically correct and
makes the intent clearer.

No functional change, but improves code readability.
