[CRIU] [PATCH 2/6] mnt: restore shared mounts in a correct shared group

[Andrei Vagin]

From: Andrei Vagin <avagin at virtuozzo.com>

Currently when we have a shared group, we set a source mount for all
of them and then we need to update a source mount when we mount a first
mount from a shared group, because a shared id can be only inherited.
