A refcounting leak was found of the original frame buffer attached to the CRTC when using the page_flip ioctl, resulting in the frame buffer never being freed. This was not obvious initially, as if the page flip subsequently re-attaches the original frame buffer, the refcounts will be balanced. However, if the original frame buffer is freed, then it will be leaked. Fix this by ensuring that we take a reference on the incoming fb, but rely on the queued work to drop that ref count.
