mm/memory_hotplug: fix kerneldoc comment for __try_online_node

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 6e768bce64fc ("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.
