hw/virtio/virtio-pmem: Fix definition of VirtIOPMEMClass

VirtIOPMEMClass's parent is VirtioDeviceClass rather than VirtIODevice.
This isn't catastrophic only because sizeof(VirtIODevice) >
sizeof(VirtioDeviceClass).

Fixes: 5f503cd9f388 ("virtio-pmem: add virtio device")
Closes: https://lists.gnu.org/archive/html/qemu-devel/2025-06/msg00586.html
