IB/srpt: Detect session shutdown reliably
The Last WQE Reached event is only generated after one or more work requests have been queued on the QP associated with a session. Since session shutdown can start before any work requests have been queued, use a zero-length RDMA write to wait until a QP has been drained. Additionally, rework the code for closing and disconnecting a session. Signed-off-by:Bart Van Assche <bart.vanassche@sandisk.com> Reviewed-by:
