[mlir][sparse] fix bug in reduction chain

Found with exhaustive testing, it is possible that a while loop
appears in between chainable for loops. As long as we don't
scalarize reductions in while loops, this means we need to
terminate the chain at the while. This also refactors the
reduction code into more readable helper methods.
