commit 6ae4edab2fbf86ec92fbf0a8f0c60b857d90d50f upstream.
Clang warns when CONFIG_BALLOON_COMPACTION is unset:
../drivers/virtio/virtio_balloon.c:963:1: warning: unused label 'out_del_vqs' [-Wunused-label] out_del_vqs: ^~~~~~~~~~~~ 1 warning generated.
Move the label within the preprocessor block since it is only used when CONFIG_BALLOON_COMPACTION is set.
