4f67d30b5e qdev: set properties with device_class_set_props() 
The following patch will need to handle properties registration during
class_init time. Let's use a device_class_set_props() setter.

spatch --macro-file scripts/cocci-macro-file.h  --sp-file
./scripts/coccinelle/qdev-set-props.cocci --keep-comments --in-place
--dir .

typedef DeviceClass;
DeviceClass *d;
expression val;

- d->props = val
+ device_class_set_props(d, val)

366844f3d1 virtio-fs: fix MSI-X nvectors calculation 
The following MSI-X vectors are required:
 * VIRTIO Configuration Change
 * hiprio virtqueue
 * requests virtqueues

Fix the calculation to reserve enough MSI-X vectors.  Otherwise guest
drivers fall back to a sub-optional configuration where all virtqueues
share a single vector.

This change does not break live migration compatibility since
vhost-user-fs-pci devices are not migratable yet.
