Currently, the object allocation function calls:
level-0: iommufd_object_alloc()
level-1: ___iommufd_object_alloc()
level-2: _iommufd_object_alloc()
So the level-1 and level-2 look inverted.
As the following change will add another level-3 helper, to make it clear:
level-0: iommufd_object_alloc()
level-1: _iommufd_object_alloc()
level-2: __iommufd_object_alloc()
level-3: ___iommufd_object_alloc()
Swap the names of the level-1 and level-2 functions.
