virtio-blk: avoid qdev property definition duplication
It becomes unwiedly to duplicate all virtio-blk qdev property
definitions due to an #ifdef. The C preprocessor syntax makes it a
little hard to resolve this cleanly but we can extract the #ifdef and
call a macro it defines later.
Avoiding duplication is important since it will only get worse when we
move the x-data-plane qdev property here too. We'd have a combinatorial
explosion since x-data-plane has its own #ifdef.
