iommufd: Correct IOMMU_HWPT_ALLOC_NEST_PARENT description 

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".

Fixes: 4ff54216 ("iommufd: Support allocating nested parent domain")
