iommu/vt-d: Restore IOMMU_CAP_CACHE_COHERENCY
In removing IOMMU_CAP_DEFERRED_FLUSH, the below referenced commit
was over-eager in removing the return, resulting in the test for
IOMMU_CAP_CACHE_COHERENCY falling through to an irrelevant option.
Restore dropped return.
Fixes: 1c18a1212c77 ("iommu/dma: Always allow DMA-FQ when iommupt provides the iommu_domain")
