drm/panel: Fix todo indentation for panel prepared/enabled cleanup

In commit d2aacaf07395 ("drm/panel: Check for already prepared/enabled
in drm_panel") the formatting for a code block was not quite
right. This caused an error when building htmldocs:

  Documentation/gpu/todo.rst:469: ERROR: Unexpected indentation.

Fix the error by using the proper syntax for a code block.
