parse.y: Change locations of NODE_DVAR in NODE_MASGN

* parse.y: Change the last location of NODE_DVAR to
  be equal to the first location of NODE_DVAR.
  NODE_DVAR of NODE_MASGN (nd_value) is an internal variable,
  so it has no length.

  e.g. The locations of the NODE_DVAR is changed:

  ```
  a.b {|(c,d)| e}
  ```

  * Before

  ```
  NODE_DVAR (line: 1, code_range: (1,7)-(1,10))
  ```

  * After

  ```
  NODE_DVAR (line: 1, code_range: (1,7)-(1,7))
  ```
