Shuhei Matsumoto 3184884f9d nvmf/tcp: Properly handle multiple iovecs in processing H2C and C2H
NVMe/TCP target had assumed the size of each iovec was io_unit_size.
Using nvme_tcp_pdu_set_data_buf() instead removes the assumption
and supports any alignment transparently.

Hence this patch moves nvme_tcp_pdu_set_data_buf() to
include/spdk_internal/nvme_tcp.h and replaces the current code to use it.

Besides, this patch simplifies spdk_nvmf_tcp_calc_c2h_data_pdu_num()
because sum of iov_len of iovecs is equal to the variable length now.

We cannot separate code movement (lib/nvme/nvme_tcp.c to include/
spdk_internal/nvme_tcp.h) and code replacement (lib/nvmf/tcp.c)
because moved functions are static and compiler give warning if
they are not referenced in lib/nvmf/tcp.c.

The next patch will add UT code.
