anv: Re-use one old BT block in reset_batch_bo_chain

We intentionally throw away all but one BT block but then we set
cmd_buffer->bt_block to ANV_STATE_NULL instead of the one we hung on to.
This causes the command buffer to immediately re-emit STATE_BASE_ADDRESS
the first time a BT is needed for no good reason.
