[PATCH] content: Minor change to clarify free_page_hint_cmd_id

From: Alexander Duyck <>

The original wording was a bit unclear and could have been misinterpreted
as indicating that VIRTIO_BALLOON_FREE_PAGE_HINT was read-only instead of
the field free_page_hint_cmd_id. To clarify that break it up into two
sentences making it clear that the field is only available if the feature
is negotiated, and that the field is read-only.
