virtio-blk: remove need for explicit x-data-plane=on option

The x-data-plane=on|off option is no longer useful because the
iothread=<iothread> option conveys the same information plus which
IOThread to use.

Do not delete x-data-plane=on|off yet as a convenience to people using
this legacy experimental option.  We will drop it in QEMU 2.2.

Instead, turn on data-plane when either x-data-plane=on or
iothread=<iothread> are used.  The following command-line uses
data-plane:

  qemu -device virtio-blk-pci,iothread=foo,drive=drive0
