KOSAKI Motohiro 4cd1a8fc3d memcg: fix possible panic when CONFIG_MM_OWNER=y ...

When mm destruction happens, we should pass mm_update_next_owner() the old mm.
 But unfortunately new mm is passed in exec_mmap().

Thus, kernel panic is possible when a multi-threaded process uses exec().

Also, the owner member comment description is wrong.  mm->owner does not
necessarily point to the thread group leader.
