ms_transform: Fix incorrect `variable shadowed' warnings

Compile below module resulting incorrect warning:

$ cat tmp.erl
-module(tmp).
-export([tmp/1]).
-include_lib("stdlib/include/ms_transform.hrl").
tmp(X) when X > 100 ->
  Y=X,
  Y;
tmp(X) ->
  ets:fun2ms(fun(Y) -> {X, Y} end).

$ erlc tmp.erl
./tmp.erl:8: Warning: variable 'Y' shadowed in ms_transform fun head

The scope for a variable is its function clause. Variables bound in one
function clause should not interfere with other function clauses.

This patch removes incorrect passing of variable bindings from one
function clause to another.
