xprtrdma: Remove rpcrdma_create_data_internal::rsize and wsize

Clean up. xprt_rdma_max_inline_{read,write} cannot be set to large values by virtue of proc_dointvec_minmax. The current maximum is RPCRDMA_MAX_INLINE, which is much smaller than RPCRDMA_MAX_SEGS * PAGE_SIZE. The .rsize and .wsize fields are otherwise unused in the current code base, and thus can be removed. Signed-off-by: Chuck Lever <[email protected]> Signed-off-by: Anna Schumaker <[email protected]>
