anv/sparse: fix block_size_B when the image is multi-sampled

This is all that's needed to make anv_sparse_bind_image_memory() work
with multi-sampled images.

The assert() we just added would have been really helpful when
debugging this.

All the dEQP tests with "sparse" in their names are passing *even*
without this patch. Real-world applications show very clear visual
corruption for sparse MSAA images bound through non-opaque binds since
only a fraction of the the actual image ends up being bound.
