[CRIU] [PATCH 4/4] dump: Skip restorer stack on re-dump

[Cyrill Gorcunov]

In case if we're checkpointing previously restored
program we might carry redundant zero-size VMA from
clone's stack used in restorer.

But restoring VMA with zero size if forbitten by mmap
call, thus simply ignore such VMA at dumping time, until
a more graceful way to resolve this problem is found.
