Wenchao Hao 0abea609f3 mm/zsmalloc: document free_zspage helper variants
After splitting __free_zspage() into a lockless core and a wrapper that
does the class-stat bookkeeping, three similarly-named helpers coexist:
free_zspage / __free_zspage / __free_zspage_lockless.

Add a comment block above them describing what each does and where it is
used, so the names are not easy to confuse.

No functional change.
