coroparse: Do not format too long path

32-bit compiler does produce warning about snprintf in the
main_config_parser_cb when path is longer than key_name.

Whole snprintf is basically no-op because key_name length is same as
error message buffer so snprintf never succeed.
Also whole problem shouldn't happen at all because too long path case
is handled by main_config_parser_cb caller.

Patch completely removes snprintf and just reports error about too long
path.
