The aio_disable_external() API is a solution for stopping I/O during critical
sections. The newer BlockDevOps->drained_begin/end/poll() callbacks offer a
cleaner solution that supports the upcoming multi-queue block layer. This
series removes aio_disable_external() from the virtio-scsi emulation code.
Patch 1 is a fix for something I noticed when reading the code.
Patch 2 replaces aio_disable_external() with functionality for safe hot unplug
that's mostly already present in the SCSI emulation code.

virtio-scsi: avoid race between unplug and transport event
virtio-scsi: stop using aio_disable_external() during unplug
