I'm not sure what happened to v1 from Prasad, so since we are
at rc2 I took a simpler approach to fix this CVE: create an
empty drive to satisfy the BlockBackend API calls.

Added Alexander's reproducer along.

Since v2:
- Reword comment (Darren)
- Add Darren R-b tag

v2: https://lore.kernel.org/qemu-devel/20211117232422.1026411-1-philmd@redhat.com/
v1: https://lore.kernel.org/qemu-devel/20210123100345.642933-1-ppandit@redhat.com/
Based-on: <20211118115733.4038610-1-philmd@redhat.com>
