[CRIU] [PATCH] mem: don't use an unitialized pointer

[Andrey Vagin]

When we are dumping pages on pre-dump, we know nothing about a parent
images, so we need to splice all memory to pipes and then decide which
should be dumped.

CID 83244 (#1 of 1): Uninitialized pointer read (UNINIT)
14. uninit_use: Using uninitialized value xfer.parent.
