RDMA/cxgb4: Notify rdma stack for IB_EVENT_QP_LAST_WQE_REACHED event
This patch sends IB_EVENT_QP_LAST_WQE_REACHED event on a QP that is in
error state and associated with an SRQ. This behaviour is incorporated
in flush_qp() which is called when QP transitions to error state.
Supports SRQ drain functionality added by commit 844bc12e6da3 ("IB/core:
add support for draining Shared receive queues")
Fixes: 844bc12e6da3 ("IB/core: add support for draining Shared receive queues")
