In the stress test of NVMe TCP (ARM platform, 6 nvme disks),
we see nvmf_tcp_req_set_state() takes quite some CPU cycles
(about 2%~3% of the nvmf_tgt process, ranking 6) moving TCP
request structure between different queues. And after some
analyzes, we think these actions can be saved. With this change
we get 1%~1.5% performance gain overall.
