Fix bug #33416, where typing a ) in a comment at EOB caused a loop (CC Mode).

Browse source 
* lisp/progmodes/cc-mode.el (c-fl-decl-start): A c-forward-syntactic-ws leaves
point inside whitespace when moving over a comment at EOB which has no
terminating LF.  Check this possibility and correct for it.
