I figured it out. I still used an older version nvme-cli which didn't
apply the hostnqn correctly. We fixed this in the meantime. With the
latest git version of nvme-cli the second I/O controller is not setup
anymore and the crash is gone. Though we still don't cleanup all
resources as the kernel module complains with
[41707.083039] nvmet_fc: nvmet_fc_exit_module: targetport list not empty
