Fix compilation error with gfio

Fix compilation error with gfio

Commit 36833fb04 replaced many usages of strncpy with snprintf.
But there is one place where new arguments were added but the function
name has not been changed. It leads to the following compilation error:

gclient.c:333:2: error: too many arguments to function ‘strncpy’
  333 |  strncpy(message, sizeof(message), "%s", status_message);
      |  ^~~~~~~
