[CRIU] [PATCH 0/3] Don't fail if tasks breed like rabbits (v3)

[Andrey Vagin]

Currently criu tries to catch all tasks for a few iterations and
then fails, so it's easy to create a fork bomb which will be never dumped.

We found that this problem can be solved with help of a freezer cgroup.

v3: restore the origin state of the freezer group in a error cases
