[BUG] Failure of AXI atomic transaction #1306

Is there an existing CVA6 bug for this?

Bug Description

In case of an AXI atomic transaction, the CVA6 crashes when we send the read data before receiving the write data of the same transaction.

Thanks for reporting. Any chance that there is a minimal test you can provide, so that we can reproduce and fix?

@JeanRochCoulon is that anything we can track in the DV Plan?
