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.
