[rfa] kod-cisco.c init sync_ids, exploit xrealloc()

[Andrew Cagney <ac131313 at cygnus dot com>]

Hello,

The attatched simplifies the setting of ``sync_ids'' by exploiting
xrealloc()'s semantics (If NULL, act like xmalloc()).  It also
eliminates a -Wuninitialized warning.

Ok?

 	``sync_ids'' eliminating uninitialized variable.
