[rds-devel] [PATCH] IB/RDS: fix the QP event handler to call rdma_notify()

[Or Gerlitz]

Change the qp event handler to call rdma_notify when getting an IB_EVENT_COMM_EST
event. This will fix the case where the RTU is not lost, ie arrives just after
the first data completion(s) where rds_connect_complete would be called twice,
and tear down the connection.
