You don't need to let-bind it to t in Emacs≥25 because its default value
is already t.  So for Emacs≥25 you should simply remove that let-binding.

Indeed: it is meant for the case where you set or let-bind that variable
to nil rather than when you set/bind it to t.

You don't need it there and let-binding it there would have no effect at
all unless the body of `c-save-buffer-state` does things like run
a recursive-edit or pause for redisplay (that var is only consulted
"outside", e.g. from `post/pre-command-hook` or
`pre-redisplay-functions`).
