There's no need to pass in a boolean to decide whether we use namespace_enter_delegated() or not. Instead, we can just check if we have CAP_SYS_ADMIN in our own user namespace. If we don't, then we have to insist on a child user namespace being passed in and we have to enter it first to get CAP_SYS_ADMIN as without CAP_SYS_ADMIN we wouldn't be able to call setns() in the first place. If we do have CAP_SYS_ADMIN, we can always enter the other namespaces first before entering the user namespace. Additionally, we don't fail anymore if we can't reset the UID/GID since a root user might not always be available in every user namespace we might enter.
