[mlir][Transform] Fix support for mapping to GPU warps and to linear ids

c59465e1 introduced mapping to warps and
linear GPU ids.

In the implementation, the delinearization basis is reversed from [x, y, z]
to [z, y x] order to properly compute the strides and allow delinearization.

Prior to this commit, we forgot to reverse it back to [x, y, z] order
before materializing the indices.

Fix this oversight.
