migration, xen: Fix block image lock issue on live migration
When doing a live migration of a Xen guest with libxl, the images for block devices are locked by the original QEMU process, and this prevent the QEMU at the destination to take the lock and the migration fail. >From QEMU point of view, once the RAM of a domain is migrated, there is two QMP commands, "stop" then "xen-save-devices-state", at which point a new QEMU is spawned at the destination. Release locks in "xen-save-devices-state" so the destination can takes them, if it's a live migration. This patch add the "live" parameter to "xen-save-devices-state" which default to true so older version of libxenlight can work with newer version of QEMU.
