[PATCH v5 04/23] migration: push Error **errp into vmstate_load()

[Arun Menon]

This is an incremental step in converting vmstate loading
code to report error via Error objects instead of directly
printing it to console/monitor.
It is ensured that vmstate_load() must report an error
in errp, in case of failure.
