It seems that recentf isn't merely a variable, but an entire mode:

Here's what it does, according to lisp/recentf.el

So if you didn't turn it on yourself explicitly and don't want the
functionality, the obvious easy thing to do is figure out where the mode
is being enabled in your init files and remove it.

If you do want it enabled, well... I won't disagree that recentf.el
should be taking more care to silence those writes...

Those writes happen in `recent-save-list`, ultimately via `write-file`:

> (write-file (expand-file-name recentf-save-file))

`write-file` does not appear to have any arguments that allow for
silencing it.

A direct fix can be done to recentf.el: it appears that you can bind
`inhibit-message` to a non-nil value and it will supress that (ala
wrapping it in a `let`), but that appears to be an Emacs 25 feature, and
wouldn't much help you anyways.

Something you can do from your init file, since `recentf-load-list` is
is a Lisp function, is to create some advice that will end up silencing
it. I'm not really sure how to construct such advice, but likely you can
find some suitable ones in a web search.
