rpc-transport/rdma: Fix 2KB as threshold size for msgs that can be transferred inline.
- Any fop/mop that can result a reply whose size is greater than this threshold allocates and submits a buffer along with the request to receive reply. Signed-off-by: Raghavendra G <raghavendra@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 513 (Introduce 0 copy rdma) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=513
