[CRIU] [PATCH 05/39] mounts: mark local root-s in the list of mount points (v2)

[Andrey Vagin]

We are going to dump nested mount namespaces. All sub-namespaces will be
restored as sub-mounts in the root mount namespace. So mi->mountpoint
will be not '/' even if a mount is root for its mntns.

v2: s/is_root/is_ns_root/
