RDMA/cxgb3: Correctly serialize peer abort path
Open MPI and other stress testing exposed a few bad bugs in handling aborts in the middle of a normal close. Fix these by: - serializing abort reply and peer abort processing with disconnect processing - warning (and ignoring) if ep timer is stopped when it wasn't running - cleaning up disconnect path to correctly deal with aborting and dead endpoints - in iwch_modify_qp(), taking a ref on the ep before releasing the qp lock if iwch_ep_disconnect() will be called. The ref is dropped after calling disconnect. Signed-off-by: Steve Wise <swise@opengridcomputing.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
