Crash in OpenSLES audio plugin

We were investigating weird crashes of our app and it led us to discovering a bug in OpenSLES audio plugin in Qt Multimedia.
File qopenslesaudioinput.cpp has a method flushBuffers which contains the following code: 

if (delta > 0)
    writeDataToDevice(m_buffers[m_currentBuffer].constData(), m_format.bytesForDuration(delta));

but it may so happen (and it was happening from time to time in our app), that ```m_format.bytesForDuration(delta)``` is larger than the QByteArray containing the data.
writeDataToDevice does QByteArray::append(data, size); so it's obvious that the size cannot be larger than the data stored under the pointer passed to this function.

We've fixed this issue by simply changing these lines to:

if (delta > 0)
   writeDataToDevice(m_buffers[m_currentBuffer].constData(), std::min(m_buffers[m_currentBuffer].size(), m_format.bytesForDuration(delta)));
