1. Add missing return in case if IOMMU ops have been already set.
2. Add check for shared IOMMU before returning an error.

Technically 1. is a fix, 2. is a new feature as sharing IOMMU is not supported today. I am ok for you to keep both in the same patch this time, but in the future please avoid mixing fixes and new feature.
