virtio-blk: Fix virtio-blk-s390 to require drive
Move the check from virtio_blk_init_pci(), where it protects only virtio-blk-pci, to virtio_blk_init(). Without that, virtio-blk-s390 initializes without a drive. I figure that can lead to null pointer dereferences. Signed-off-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>
