Subject: [PATCH] scsi: esp: fix migration
Commit 926cde5 ("scsi: esp: make cmdbuf big enough for maximum CDB size",
2016-06-16) changed the size of a migrated field. Split it in two
parts, and only migrate the second part in a new vmstate version.
Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
(cherry picked from commit cc96677469388bad3d66479379735cf75db069e3)
