Subject: [PATCH] Scene Graph: Fixed memory leak in
 QSGBatchRenderer::Renderer::map()

In the uncommon case (m_context->hasBrokenIndexBufferObjects()
|| m_visualizeMode != VisualizeNothing) of mapping a buffer, malloc is
called without first freeing the previous malloc.

Regression was introduced with:
    qt5 commit: 9347499e78f03710eaf24af3c1e7ac650d0ef81d
    qtdeclarative commit: a371bac3fba73f92aaa63a68d8ab1ae81a1d1031
