From: Yangyang Li <liyangyang20@xxxxxxxxxx>
When exiting "for loop", the actual value of pi will be
increased by 1, which is compatible with the next calculation.
But when pi is equal to "ci + hr_cq-> ib_cq.cqe", the "break"
was called and the pi is actual value, it will lead one cqe
still existing, so the "==" should be modify to ">".
