The CQ (completion queue) descriptors were updated by hardware, and then
scanned by driver to retrieve hardware completion status.
This patch enhances robustness by following:
1. replace while (true) with a finite loop to avoid potential dead loop.
2. check the csq_head field in CQ descriptor to avoid status array
overflows.
