When a `cl-labels' form is wrapped with `lexical-let', it runs
`cl--function-convert' instead of `cl--labels-convert'.
So, `cl--function-convert' also needs to be fixed like the ones
Stefan did in `cl--labels-convert'[1], doesn't it?  I tried the
attached patch and verified it fixes not only the `cl-labels'
bug but also the `cl-flet' bug[2].

(lexical-let (var)
  (cl-flet ((fn (arg) arg))
    (apply #'fn (list "arg"))))
 => apply: Symbol's function definition is void: fn
