migration: push Error **errp into vmstate_load_state()
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_state() must report an error
in errp, in case of failure.

The errors are temporarily reported using error_report_err().
This is removed in the subsequent patches in this series,
when we are actually able to propagate the error to the calling
function using errp. Whereas, if we want the function to exit on
error, then error_fatal is passed.
