For example doing "lxc-execute -n tmpct /bin/bash" will call setup_kmsg(), but
in this case rootfs->mount/dev directory doesn't even exist so the call to
symlink fails with ENOENT. Commit f62b3449 made this failure not fatal, but
we should not even try it when we know it will fail. See similar code in
setup_tty(), setup_console(), etc.
