[PATCH v7 4/4] intel_iommu: make type match |

From: Clément Mathieu--Drif <clement.mathieu--drif@eviden.com>
The 'level' field in vtd_iotlb_key is an unsigned integer.
We don't need to store level as an int in vtd_lookup_iotlb.
This is not an issue by itself, but using unsigned here seems cleaner.
