<pre>commit 5f3ee21a307a4ff4db189bd53e58a70ec01ee6bc

sna: Nullify pixmap->devPrivate.ptr after promoting CPU bo to GPU
When we convert a CPU bo into a GPU bo, we need to remove any dangling
shadow pointers we use for devPrivate.ptr. Whilst the bo remains alive
these are incoherent, but if we ever replace the GPU bo (for example to
change tiling for DRI2) then the dangling pointer becomes invalid and
will explode on next use.
