[PATCH v2] mm, docs: fix comments that mention mem_hotplug_end()

[Yun-Ze Li <p76091292@gs.ncku.edu.tw>]

Comments that mention mem_hotplug_end() are confusing as there is no
function called mem_hotplug_end(). Fix them by replacing all the
occurences of mem_hotplug_end() in the comments with mem_hotplug_done().
