sdpscanner: fix potential unwanted truncation for SDP_TEXT_STR{8,16,32}

QByteArray::resize() treats all negative parameters as a request for
a zero length. So the code

  text.resize(text.indexOf('\0'));

can completely erase the text if there is no '\0' in it.

Fix it by explicitly checking the return value of QByteArray::indexOf().
