iommufd: Add enforced_cache_coherency to iommufd_hw_pagetable_alloc()
Logically the HWPT should have the coherency set properly for the device
that it is being created for when it is created.
This was happening implicitly if the immediate_attach was set because
iommufd_hw_pagetable_attach() does it as the first thing.
Do it unconditionally so !immediate_attach works properly.
