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.
