[Qemu-devel] [PATCH 56/61] virtio-9p : cleanup : QOM casts.

[fred.konrad@greensocs.com]

From: KONRAD Frederic <fred.konrad@greensocs.com>

As the virtio-9p-pci is switched to the new API, we can use QOM casts.
This shouldn't been applyied before virtio-9p-pci refactoring as its
VirtIODevice was not a QOM object.
