    Not all of the calls to send_write are properly handling the error case
    and unmapping the outstanding ib_dma_maps when an error is encountered.
    Also, send_write is not returning en error when the connection is closed
    while it is sleeping waiting for free slots on the send queue.  This
    patch corrects the calls to send_write that did not cleanup after
    themselves and now returns an error if the connection is closed in all
    cases.
    
    This fixes bug 1824.
