cxgb3 - Set the CQ_ERR bit in CQ contexts.
The cxgb3 driver is incorrectly configuring the HW CQ context for CQ's
that use overflow-avoidance. Namely the RDMA control CQ. This results
in a bad DMA from the device to bus address 0. The solution is to set
the CQ_ERR bit in the context for these types of CQs.
