iommufd: Correct IOMMU_HWPT_ALLOC_NEST_PARENT description 

commit b5f9e63278d6 ("iommufd: Correct IOMMU_HWPT_ALLOC_NEST_PARENT description") upstream

The IOMMU_HWPT_ALLOC_NEST_PARENT flag is used to allocate a HWPT. Though
a HWPT holds a domain in the core structure, it is still quite confusing
to describe it using "domain" in the uAPI kdoc. Correct it to "HWPT".

Intel-SIG: commit b5f9e63278d6 ("iommufd: Correct IOMMU_HWPT_ALLOC_NEST_PARENT description)"
Backport to support Intel QAT live migration for in-tree driver

Fixes: 4ff542163397 ("iommufd: Support allocating nested parent domain")
