sna: Reset the source counter if we completely dirty the CPU pixmap
For a long lived pixmap which we are repeatedly using for upload and
copying to other pixmaps, we don't want to keep to maintain a GPU
buffer. So instead, reset the source counter if we discard the GPU bo
and treat the pixmap as purely CPU.
