io/fs: fix reference to WalkFunc

Browse source 
The comment explains differences between WalkDirFunc and WalkFunc,
but when this code moved out of path/filepath, we forgot to change
the reference to be filepath.WalkFunc. Fix that.

(The text should not be deleted, because path/filepath does not
contain this type - WalkDirFunc - nor this text anymore.)

Pointed out by Carl Johnson on CL 243916 post-submit.

For #41190.
