Alexey Marchuk ada9333423 nvme/tcp: Report correct max sge 
NVME TCP driver supports up to 16 sge elements
while only 1 sge is reported - that leads to
unnecessary requests split which degrades perf.
Also pass correct iovcnt to nvme_tcp_build_iovs -
it should be 32. Otherwise, pdu header consumes
1 iov and data is written partially.
Add a check that at least data_len bytes were
appended to the socket iovs and fail request
otherwise.
