locking/atomic: remove fallback comments

Currently a subset of the fallback templates have kerneldoc comments,
resulting in a haphazard set of generated kerneldoc comments as only
some operations have fallback templates to begin with.

We'd like to generate more consistent kerneldoc comments, and to do so
we'll need to restructure the way the fallback code is generated.

To minimize churn and to make it easier to restructure the fallback
code, this patch removes the existing kerneldoc comments from the
fallback templates. We can add new kerneldoc comments in subsequent
patches.

There should be no functional change as a result of this patch.
