This patch is the first patch of the patch series.
The purpose of this patch series is to correct the bug of
nvme_tcp_pdu_set_data_buf() when the multiple iovecs array is
passed, to share nvme_tcp_pdu_set_data_buf() between NVMe/TCP
initiator and target, and utilize nvme_tcp_pdu_set_data_buf()
not only for C2H and H2C but also in-capsule data in NVMe/TCP
target.
This patch is necessary to satisfy the second requirement, to
share nvme_tcp_pdu_set_data_buf() between NVMe/TCP initiator and target
because struct nvme_tcp_req and struct spdk_nvmf_tcp_req are different.
Four variables, iov, iovcnt, data_offset, and data_len are common,
and hence this patch changes the parameters of nvme_tcp_pdu_set_data_buf()
to accept them.
The bug is fixed in the next patch and tested in after the next patch.
