dirstate: Appease pytype

test-check-pytype.t was failing since 98c0408324e6:

   File "/home/simon/projects/hg/mercurial/dirstatemap.py", line 572, in
   addfile: unsupported operand type(s) for &: 'size: None' and
   'rangemask: int' [unsupported-operands]
       No attribute '__and__' on 'size: None' or '__rand__' on 'rangemask: int'
   File "/home/simon/projects/hg/mercurial/dirstatemap.py", line 573, in
   addfile: unsupported operand type(s) for &: 'mtime: None' and
   'rangemask: int' [unsupported-operands]
       No attribute '__and__' on 'mtime: None' or '__rand__' on 'rangemask: int'

`None` is the default value of the `size` and `mtime` parameters of the
`addfile` method. However, the relevant lines are only used in a code path
where those defaults are never used. These `size` and `mtime` are passed
to `DirstateItem.new_normal` which (in the C implementation) calls
`dirstate_item_new_normal` which uses:

    PyArg_ParseTuple(args, "iii", &mode, &size, &mtime)

So `None` values would cause an exception to be raised anyway.
The new `assert`s only move that exception earlier, and informs pytype
that we expect `None` to never happen in this code path.
