vmstate: Avoid seeking
Seeking on vmstate save/load does not work if the underlying file is a
stream. We could try to make all QEMUFile* forward-seek-aware, but first
attempts in this direction indicated that it's saner to convert the few
qemu_fseek-on-vmstates users to plain reads/writes.
This fixes various subtle vmstate corruptions where unused fields were
involved.
