  [mlir][vector] Fix n-d transfer write distribution (#83215)

Currently n-d transfer write distribution can be inconsistent with
distribution of reductions if a value has multiple users, one of which
is a transfer_write with a non-standard distribution map, and the other
of which is a vector.reduction.

We may want to consider removing the distribution map functionality in
the future for this reason.
