linux-cp: fix crash on processing dump of routes
nl_route_add() recently started to use its optional argument to check
whether replace flag is set for the message. When notification messages
are processed, the argument is a pointer to the corresponding message
info. However, when dump replies are processed, the argument is a null
pointer. This leads to null pointer dereference and crash when dump of
routes is processed.
With this fix, check for replace flag only if message info was passed
to nl_route_add(). Otherwise, assume the flag is not set. Dump replies
do not have it set.
Type: fix
