state: Fix "pack" returning freed data for DTB backend
`state_backend_format_dtb_pack()` passes a buffer containing state
packed in flattened DTB format back to its caller via its `buf`
parameter. It then frees the buffer before returning. This means the
caller (`state_save()`) will be working on freed buffer contents before
freeing the buffer a second time itself. Fix it by removing the
spurious call to `free()`.
This should fix a bug reported by Norbert Wiedmann in
<http://lists.infradead.org/pipermail/barebox/2017-April/029980.html>.
