Rui Chang 60af3c00d8 nvmf/tcp: optimize nvmf_tcp_req_set_state() to reduce cpu usage ... 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.
