Avihai Horon d0ad271a76 migration/postcopy: Ensure postcopy_start() sets errp if it fails ... There are several places where postcopy_start() fails without setting errp. This can cause a null pointer de-reference, as in case of error, the caller of postcopy_start() copies/prints the error set in errp. Fix it by setting errp in all of postcopy_start() error paths.
