make W=1 generates the following warning for try_online_node

mm/memory_hotplug.c:1087: warning: expecting prototype for try_online_node(). Prototype was for __try_online_node() instead

Commit b9ff036082cd ("mm/memory_hotplug.c: make add_memory_resource use
__try_online_node") renamed the function but did not update the associated
kerneldoc. The function is static and somewhat specialised in nature
so it's not clear it warrants being a kerneldoc by moving the comment
to try_online_node. Hence, leave the comment of the internal helper in
place but leave it out of kerneldoc and correct the function name in
the comment.
