From: John Snow <js...@redhat.com>
Amazingly, we weren't doing this before.
Make sure we migrate the IDEState structure that belongs to
the AHCIDevice.IDEBus structure during migrations.
No version numbering changes because AHCI is not officially
migratable (and we can all see with good reason why) so we
do not impact any official builds by altering the stream and
leaving it at version 1.
This fixes the rerror=stop/werror=stop test case where we wish
to migrate a halted job. Previously, the error code would not
migrate, so even if the job completed successfully, AHCI would
report an error because it would still have the placeholder
error code from initialization time.
