Fast Memory Registration (fmr) is used to register for rdma an sg whose elements are not linearly sequential after dma mapping. The IB verbs layer provides an "all dma memory MR (memory region)" which can be used for RDMA-ing a dma linearly sequential buffer. Change the code to use the dma mr instead of doing fmr when dma mapping produces a single dma entry sg.
