[CRIU] [PATCH] dump: clean up shared_fdtable

[Andrey Vagin]

It's cleaned up accoding with following statements:
* files_id can't be zero (look at dump_task_kobj_ids)
* item->ids is allocated for all non-dead tasks
* a parent can't be dead

In addition here is a tiny coding stype fix.

Fixes: 475bb1e77522 ("rst: Evaluate per-task clone mask early")
