It prints the error instead of setting it when connect_to_sdog() fails. Fix that. While there, return the value of connect_to_sdog() like we do elsewhere, instead of -EIO. No functional change, as connect_to_sdog() returns no other error code. Many more suspicious uses of error_report() and error_report_err() remain in other functions. Left for another day.
