[PATCH v4 1/4] intel_iommu: fix FRCD construction macro

[CLEMENT MATHIEU--DRIF]

From: Clément Mathieu--Drif <clement.mathieu--drif@eviden.com>

The constant must be unsigned, otherwise the two's complement
overrides the other fields when a PASID is present.

Fixes: 1b2b12376c8a ("intel-iommu: PASID support")
