[PULL 2/2] hw/core: Allow setting 'virtio-blk-device.scsi' property on OSX host |

From: Philippe Mathieu-Daudé <address@hidden>
Commit ed65fd1a2750 ("virtio-blk: switch off scsi-passthrough by
default") changed the default value of the 'scsi' property of
virtio-blk, which is only available on Linux hosts. It also added
an unconditional compat entry for 2.4 or earlier machines.
Trying to set this property on a pre-2.5 machine on OSX, we get:
Unexpected error in object_property_find() at qom/object.c:1201:
qemu-system-x86_64: -device virtio-blk-pci,id=scsi0,drive=drive0: can't
apply global virtio-blk-device.scsi=true: Property '.scsi' not found
Fix this error by marking the property optional.
Fixes: ed65fd1a27 ("virtio-blk: switch off scsi-passthrough by default")
