There is a bug of v3 hw development version. When AXI error happen, hw may return an abnormal CQ that IPTT value is 0xffff. This will cause IPTT out-of-bounds reference. This patch adds a check of IPTT in cq_tasklet_v3_hw() and discards invalid slot. This workaround scheme is just to enhance fault-tolerance of the driver. So, we will apply this scheme for all version of v3 hw, although release version has fixed this SoC bug.
