    Fix OpenSSL private key passphrase notices
    
    Clear error stack on successful certificate loading in
    tls_ctx_load_cert_file_and_copy() and handle errors also for
    PEM_read_bio_PrivateKey() call in tls_ctx_load_priv_file().
    
    Due to certificate loading possibly leaking non-fatal errors on OpenSSL
    error stack, and some slight oversights in error handling, the
    
    >PASSWORD:Verification Failed: 'Private Key'
    
    line was never produced on the management channel for PEM formatted keys.
