virtio_scsi_dataplane_stop() calls blk_drain_all(), which invokes ->drained_begin()/->drained_end() after we've already detached the host notifier. virtio_scsi_drained_end() currently attaches the host notifier again and leaves it dangling after dataplane has stopped. This results in the following assertion failure because virtio_scsi_defer_to_dataplane() is called from the IOThread instead of the main loop thread: qemu-system-x86_64: ../softmmu/memory.c:1111: memory_region_transaction_commit: Assertion `qemu_mutex_iothread_locked()' failed.
