Subject: De-pessimize QTlsBackendOpenSSL::clearErrorQueue()
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

We don't need to format the error messages into a QString just to
clear the error queue. Just looping over q_ERR_get_error() does the
trick, too, and isn't less readable.

Pick-to: 6.3
