[PATCH] drivers: virtio: Make out_del_vqs dependent on BALLOON_COMPACTION

[Vincenzo Frascino]

out_del_vqs label is currently used only when BALLOON_COMPACTION
configuration option is enabled. Having it disabled triggers the
following warning at compile time:

drivers/virtio/virtio_balloon.c: In function âvirtballoon_probeâ:
drivers/virtio/virtio_balloon.c:963:1: warning: label âout_del_vqsâ
defined but not used [-Wunused-label]
  963 | out_del_vqs:
      | ^~~~~~~~~~~

Make out_del_vqs dependent on BALLOON_COMPACTION to address the
issue.
