Tweak Fdocumentation's error for an undefined function
* src/doc.c (Fdocumentation): Restore the pre-25 behavior
of signalling a void-function error for an undefined function.
This seems cleaner than Emacs 25's "invalid-function: nil" error,
which was (probably) an unintended consequence of changes to
Findirect_function.
