gtp_echo_responder: report invalid chars present in node-feautres cmdline arg as errorHEADmaster
from "man strtoul": """ If endptr is not NULL, strtoul() stores the address of the first invalid character in *endptr. In particular, if *nptr is not '\0' but **endptr is '\0' on return, the entire string is valid. """ Fixes: ae81195418ebed5280d0753d037df483bb914a0b Change-Id: I89d26a575ef81ee17483db035924354588d9d094
