In nspawn.c's run_container() the child_netns_fd = receive_one_fd(...) failure path logged 'r' instead of the negative errno returned in child_netns_fd, so the actual error from receive_one_fd was being overwritten by whatever 'r' happened to hold. The other receive_one_fd call sites in the same function use the returned fd variable directly (mntns_fd, etc.), so align this one. In shared/nsresource.c's nsresource_add_cgroup() the cgroup_fd_idx = sd_varlink_push_dup_fd(...) failure path logged userns_fd_idx, which is the previous successful push's index, not the negative errno we just got from pushing cgroup_fd. Log cgroup_fd_idx instead. Both were flagged by static analysis (#41709) and match the immediately preceding userns_fd-path pattern that was presumably copy-pasted. Refs #41709.
