Mark Cave-Ayland ff4a1daba6 esp: fix setting of ESPState mig_version_id when launching QEMU with -S option ... If QEMU is launched with the -S option then the ESPState mig_version_id property is left unset due to the ordering of the VMState fields in the VMStateDescription for sysbusespscsi and pciespscsi. If the VM is migrated and restored in this stopped state, the version tests in the vmstate_esp VMStateDescription and esp_post_load() become confused causing the migration to fail. Fix the ordering problem by moving the setting of mig_version_id to a common esp_pre_save() function which is invoked first by both sysbusespscsi and pciespscsi rather than at the point where ESPState is itself serialised into the migration stream.
