64 bit props used 32 bit callbacks in two places, leading to broken
feature bits on virtio (example: got 0x31000000000006d4 which is
obviously bogus). Fix this.
Fixes: fdba6d96 ("qdev: add 64bit properties")

With that patch a pre-v1-patches save file loads and works. (Without this
patch the guest loads, but virtio is broken and all I/O hangs)

Ping? I think this should go into 2.4-rc1.
