Chunsong Feng 0db0c443df nvmf/rdma: Improve read performance in DIF strip mode
The rdma buffer for stripping DIF metadata is added. CPU strips the DIF
metadata and copies it to the rdma buffer, improving the rdma write
bandwith. The network bandwidth during 4KB random read test is increased
from 79 Gbps to 99 Gbps, the IOPS is increased from 2075K to 2637K.

Fixes issue #2418
