pid_namespace: pidns_get() should check task_active_pid_ns() != NULL
commit d23082257d83e4bc89727d5aedee197e907999d2 upstream.
pidns_get()->get_pid_ns() can hit ns == NULL. This task_struct can't
go away, but task_active_pid_ns(task) is NULL if release_task(task)
was already called. Alternatively we could change get_pid_ns(ns) to
check ns != NULL, but it seems that other callers are fine.
