connect-all fails when there is no .nvme keyring because CONFIG_NVME_TCP_TLS and CONFIG_NVME_HOST_AUTH are not enabled

Since nvme-cli 2.11 I am seeing this issue in the systemd CI where nvme-cli is used. The nvme-ctp is loaded module is loaded:

[    4.741966] TEST-84-STORAGETM.sh[577]: + modprobe -v nvmet-tcp
[    4.750298] TEST-84-STORAGETM.sh[580]: insmod /lib/modules/6.11.5-cloud-amd64/kernel/drivers/nvme/target/nvmet.ko.xz

The command, which used to work with nvme-cli 2.10, started failing since Debian upgraded to 2.11:

6234s [   25.416521] TEST-84-STORAGETM.sh[548]: + nvme connect-all -t tcp -a 127.0.0.1 -s 16858 --hostid=158f4d7d-6759-499e-b260-b152e49fa9a2

Is enabling those kconfigs and setting up TLS keys required now to use nvme connect-all -t tcp?

This is on kernel 6.11.5. Note that Debian does not enable CONFIG_NVME_TCP_TLS and CONFIG_NVME_HOST_AUTH

Sorry about this. From a quick glance, I'd say it should not fail hard. Let me look into it.

I suppose I should do a libnvme 1.11.1 release after merging the fix.

That would be very nice, thanks for the quick fix!
