netfilter: nf_conntrack_pptp: prevent buffer overflows in debug code commit 4c559f15efcc43b996f4da528cd7f9483aaca36d upstream. Dan Carpenter says: "Smatch complains that the value for "cmd" comes from the network and can't be trusted." Add pptp_msg_name() helper function that checks for the array boundary.
