[mlir][vector] Fix lowering of permutation maps for transfer_write op

The lowering of transfer write permutation maps didn't match the op definition:
https://github.com/llvm/llvm-project/blob/93ccccb00d9717b58ba93f0942a243ba6dac4ef6/mlir/include/mlir/Dialect/Vector/IR/VectorOps.td#L1476

Fix the lowering and add a case to the integration test in
order to enforce the correct semantic.
