[PATCH] fs: cleanup slight list_entry abuse

list_entry is just a wrapper for container_of, but it is arguably
wrong (and slightly confusing) to use it when the pointed-to struct
member is not a struct list_head. Use container_of directly instead.

Most of these predate git. If I'm the only one who has been confused
by this in 10 years, maybe it's not worth the churn.
