[qemu-s390x] [PULL 07/19] hw/s390x/virtio-ccw: Consolidate calls to virtio_ccw_unrealize()

[Cornelia Huck]

From: Thomas Huth <address@hidden>

Currently, every virtio-ccw device explicitely sets its unrealize
function to virtio_ccw_unrealize() in its class_init function.
We can simplify this by using a common unrealize function, just like
it is already done for the realize functions.
