monitor: Drop handler_8 and handler_9 Commit 79c4f6b08009a1d23177c2be8bd003253cf3686a added handler_8 and handler_9 handling, but there isn't any command handler with those number of arguments. Just drop them. Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
