intel: rework command buffer waiting
When a bo is submitted, we need the submission sequence number which we can
wait for. However, the kernel does not return the seqno. We have to keep the
bo around and wait for the bo. This fixes
xglQueueSubmit(..., cmd, ...);
xglDeviceWaitIdle(...);
xglDestroyObject(..., cmd);
xglDeviceWaitIdle(...);
where the second wait waited for a destroyed cmd buffer.
