Subject: [PATCH 5.4 001/123] virtio_balloon: Adjust label in virtballoon_probe

From: Nathan Chancellor <natechancellor@...il.com>

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.
