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.
Fixes: f09943fefe6b ("[NETFILTER]: nf_conntrack/nf_nat: add PPTP helper port")
