Pablo Neira Ayuso 4c559f15ef netfilter: nf_conntrack_pptp: prevent buffer overflows in debug code
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: f09943fefe ("[NETFILTER]: nf_conntrack/nf_nat: add PPTP helper port")
