CC Mode: Remove search limit to fontify first decl in xdisp.c

An unneeded 10,000 character search limit prevents the full
fontification of the first declaration of xdisp.c, since the
introductory commentary is longer than that.

* lisp/progmodes/cc-engine (c-find-decl-spots): Remove the
10,000 char limit.
