r600g: only set depth bit for hw accessible depth buffers.
If we get a sw accessible buffer like the S8 texture we end up doing depth tracking on it when there is no need since we won't ever bind it to the hardware. This leads to a sw fallback in the transfer destruction which leads to and endless recusion loop of fail in transfer destroy. Signed-off-by: Dave Airlie <[email protected]>
