RDMA/cxgb4: Fix race in fini path
There exists a race condition where the app disconnects, which initiates an orderly close (via rdma_fini()), concurrently with an ingress abort condition, which initiates an abortive close operation. Since rdma_fini() must be called without IRQs disabled, the fini can be called after the QP has been transitioned to ERROR. This is ok, but we need to protect against qp->ep getting NULLed.
