QSGBatchRender: avoid crash if buffer shrinks
The QRhiBuffer does not shrink; thus we can end up with
buffer->buf->size > buffer->size. This would subsequently lead to an
out-of-bounds memory access, and a crash. Fix this by using the
uploadStaticBuffer overload which takes the size.
As a drive-by, remove pointless QByteArray::fromRawData call.
