parse.y: Fix the locations of NODE_BLOCK_PASS

* parse.y (arg_blk_pass): Update the first location of
    NODE_BLOCK_PASS if nd_head is assigned.

  e.g. The locations of NODE_BLOCK_PASS is fixed:

  ```
  a(1, &:to_s)
  ```

  * Before

  ```
  NODE_BLOCK_PASS (line: 1, first_lineno: 1, first_column: 5, last_lineno: 1, last_column: 11)
  ```

  * After

  ```
  NODE_BLOCK_PASS (line: 1, first_lineno: 1, first_column: 2, last_lineno: 1, last_column: 11)
  ```
