[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.

We took the offending commit via netdev, so I feel responsible. Please
LMK if anyone else is planning to apply this fix, otherwise we'll take
it and ship it to Linus on Thursday (19th).
