parse.y: Fix location of asgn node

* parse.y (new_op_assign_gen): Fix location of asgn node.
  Assignable node (e.g. NODE_LASGN) is generated before rhs
  is generated, so we reset the location when nd_value of
  asgn is fixed.

  e.g. :

  ```
  a -= 10
  ```

  * Before

  ```
  NODE_DASGN_CURR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 1)
  ```

  * After

  ```
  NODE_DASGN_CURR (line: 1, first_lineno: 1, first_column: 0, last_lineno: 1, last_column: 7)
  ```
