Shuhei Matsumoto 2821762a60 dif: Support a single iovec for data buffer in spdk_dif_set_md_interleave_iovs
Currently iSCSI target have used a single contiguous data buffer
both for read and write I/O. Hence spdk_dif_set_md_interleave_iovs
accepts a single contiguous data buffer and its size as arguments.

On the other hand, NVMe-TCP target recently has changed to use
SGL data buffer instead.

DIF strip and insert will be supported in NVMe-TCP target next,
and updating spdk_dif_set_md_interleave_iovs to accept SGL data
buffer will be helpful.

This patch changes the interface of spdk_dif_set_md_interleave_iovs,
but allows only a single iovec. The next patch will allow multiple
iovecs.
