A callback return value < 0 means there was an error, so print out an error message. But a rv > 0 is used by the mount_unknown_fs functions to say "we found the one we want, stop here."
Document this, and only print an error message if rv < 0. Otherwise, lxc-create -B lvm --fstype ext3 -t ubuntu -n u1 will print an (innocuous) error message about being unable to parse the config value 'ext3'.
