gtp_echo_responder: report invalid chars present in node-feautres cmdline arg as error
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.
"""
