Always limit the size of the RDMA transfer to the maximum amount supported

Просмотр исходного кода 
by the BTL (btl_max_rdma_size). Now the PUT protocol is pipelined even if there
is just one network between the 2 peers. Unfortunately, this problem is present
the 1.1 (no pipeline for the PUT protocol).
