iommufd: Deal with IOMMU_HWPT_FAULT_ID_VALID in iommufd core

Browse source

IOMMU_HWPT_FAULT_ID_VALID is used to mark if the fault_id field of
iommu_hwp_alloc is valid or not. As the fault_id field is handled in
the iommufd core, so it makes sense to sanitize the
IOMMU_HWPT_FAULT_ID_VALID flag in the iommufd core, and mask it out
before passing the user flags to the iommu drivers.
