PM: hibernate: Clean up kernel-doc comment style usage

Several static functions in kernel/power/swap.c were described using the
kernel-doc comment style (/** ... */) even though they are not exported
or referenced by generated documentation. This led to kernel-doc warnings
and stylistic inconsistencies.

Convert these unnecessary kernel-doc blocks to regular C comments,
remove comment blocks that are no longer useful, relocate comments to
more appropriate positions where needed, and fix a few "Return:"
descriptions that were either missing or incorrectly formatted.

No functional changes.
