[PATCH v2] lib/bitmap: Fix bitmap_scatter() and bitmap_gather() kernel doc

[Herve Codina]

The make htmldoc command failed with the following error
  ... include/linux/bitmap.h:524: ERROR: Unexpected indentation.
  ... include/linux/bitmap.h:524: CRITICAL: Unexpected section title or transition.

Move the visual representation to a literal block.

Fixes: de5f84338970 ("lib/bitmap: Introduce bitmap_scatter() and bitmap_gather() helpers")
Reported-by: Stephen Rothwell <sfr@xxxxxxxxxxxxxxxx>
Closes: https://lore.kernel.org/linux-kernel/20240312153059.3ffde1b7@xxxxxxxxxxxxxxxx/
