anv/tr-tt: assert the bind size is a multiple of the granularity

If the size here is not a multiple of the granularity (64kb) then
we'll miss our "pages" estimation by 1. We could fix this with
DIV_ROUND_UP() or by simply putting a "+1" there, but the upper layers
should now be preventing this case so let's just put the assertion
here.

Previously it was possible to hit this case with Zink by running
under certain conditions piglit/arb_sparse_buffer-basic.
