[PATCH 2/3] balloon: switch from C struct to table

["Michael S. Tsirkin" <mst@redhat.com>]

Since old balloon uses little endian in legacy mode violating
the rule that leXX means guest endian in legacy mode,
let's not use leXX for that.

Switch from C struct to a table and document endian-ness
explicitly.
