NVMe-oF cannot connect

When the nvme subsystem has all portals in connecting state and we try to attach a new volume to that same subsystem it will fail.

One way to reproduce this issue is to configure LVM+nvmet with:
  use_multipath_for_image_xfer = true
  iscsi_secondary_ip_addresses = 127.0.0.1
  target_secondary_ip_addresses = 127.0.0.1
  lvm_share_target = true
  nvmeof_conn_info_version = 2

Then we attach 2 volumes to an instance and delete the instance.

Then we create another instance and try to connect a volume. This will fail.
