plugins/screencast: Avoid resetting m_dmabufParams when resizing the stream

Browse source 
ScreenCastStream::onStreamAddBuffer() can be called before the stream
params are updated. This is problematic because that function expects a
valid m_dmabufParams.

The reason why m_dmabufParams is reset is to force the onStreamParamChanged()
function to check whether dmabufs can be still allocated with the new size.
