svcrdma: Reduce size of sge array in struct svc_rdma_op_ctxt

Browse source 
The sge array in struct svc_rdma_op_ctxt is no longer used for
sending RDMA Write WRs. It need only accommodate the construction of
Send and Receive WRs. The maximum inline size is the largest payload
it needs to handle now.
