[ Upstream commit 679c54f2de672b7d79d02f8c4ad483ff6dd8ce2e ]

Use command_id instead of req->tag in trace_nvme_complete_rq(),
because of commit e7006de6c238 ("nvme: code command_id with a genctr
for use authentication after release"), cmd->common.command_id is set to
((genctl & 0xf)< 12 | req->tag), no longer req->tag, which makes cid in
trace_nvme_complete_rq and trace_nvme_setup_cmd are not the same.

Fixes: e7006de6c238 ("nvme: code command_id with a genctr for use authentication after release")
