[PATCH v2 19/22] iotests: Revert "iotests: use -ccw on s390x for 040, 139, and 182"

[Alex Bennée]

From: Laurent Vivier <laurent@vivier.eu>

Commit f1d5516ab583 introduces a test in some iotests to check if
the machine is a s390-ccw-virtio and to select virtio-*-ccw rather
than virtio-*-pci.

We don't need that because QEMU already provides aliases to use the correct
virtio interface according to the machine type.

This patch removes all virtio-*-pci and virtio-*-ccw to use virtio-*
instead and remove get_virtio_scsi_device().
This also enables virtio-mmio devices (virtio-*-device)
