[CRIU] [PATCH 0/3] Cleanup shmem restoring code

[Pavel Emelyanov]

The shmem restoring code used to be scattered between criu and
restorer, but after Andrey's patches using memfd it's no longer 
such. Clean the code a little bit localizing it in shmem.c.

Also fix not-yet-fired BUG with patch #2 :)

Thanks,
Pavel
