When LUN with no io_channels is being hotremoved, the hotremove poller was being started on the core pointed by lun->lcore. However, this field is only valid when there are io_channels open. For example, when user tries to delete a bdev that's attached to an unused vhost controller (no io_channels ever opened) the scsi layer could start a hotremove poller on lun->lcore == 0. If SPDK runs on a different cpuset - not containing CPU0 - SPDK could even segfault.
