time: tick-oneshot: Add missing Return and parameter descriptions to kernel-doc

Several functions in kernel/time/tick-oneshot.c are missing parameter and
return value descriptions in their kernel-doc comments. This causes
warnings during doc generation.

Update the kernel-doc blocks to include detailed @param and Return:
descriptions for better clarity and to fix kernel-doc warnings.  No
functional code changes are made.
