[CRIU] [PATCH 1/2] page-server: don't return a server pid from page-server

[Andrei Vagin]

From: Andrei Vagin <avagin at virtuozzo.com>

This patch fixes an exit code if a page-server is started
as a daemon. Now the criu exits with a pid of a page server,
it's meaningless, because pid is usually bigger than 128.
