[RFC for Linux v4 1/2] virtio_balloon: Add VIRTIO_BALLOON_F_CONT_PAGES and inflate_cont_vq

This commit adds a new flag VIRTIO_BALLOON_F_CONT_PAGES to virtio_balloon. Add it adds a vq inflate_cont_vq to inflate continuous pages. When VIRTIO_BALLOON_F_CONT_PAGES is set, try to allocate continuous pages and report them use inflate_cont_vq. Signed-off-by: Hui Zhu ---
