Avoid needless flush emits in the blockhandler.
The EmitFlush in i830_dri.c was added as a pageflipping workaround, and was
noted to not even be sufficient then. There's no reason for it to be there,
so it's removed. After that, we just have to not emit an MI_FLUSH if we
already had, and cursor movement no longer bashes memory manager.
