global: fix err_to_stderr can't work when it was configured to false

function `set_stderr_level(-1, -1)` set m_stderr_log and m_stderr_crash to -1,
regardless of whether `err_to_stderr` is set to false or not, so logs will be
 always written to stderr. fix it as the same way as handle_conf_change does.
