I had the same problem before, mine is CentOS, and when I created
/iscsi/create iqn_bla-bla
it goes
ocal LIO instance already has LIO configured with a target - unable to continue
then finally the solution happened to be, turn off target service
systemctl stop target
systemctl disable target
somehow they are doing the same thing, you need to disable 'target' service (targetcli) in order to allow gwcli (rbd-target-api) do it's job.
Cheers

Could you send the output of
targetcli ls
?
What distro are you using?
You might just have a target setup from a non gwcli source. Maybe from
the distro targetcli systemd tools.
