Linux Virtualization - Dec 2013 - [PATCH] drivers: virtio: Mark function virtballoon_migratepage() as static in virtio_balloon.c

Mark the function virtballoon_migratepage() as static in
virtio_balloon.c because it is not used outside this file.

This eliminates the following warning in virtio_balloon.c:
drivers/virtio/virtio_balloon.c:372:5: warning: no previous prototype for
?virtballoon_migratepage? [-Wmissing-prototypes]
