[PATCH 3/3] migration: Put Error **errp parameter last

[Markus Armbruster <armbru@redhat.com>]

qapi/error.h's big comment:

 * - Functions that use Error to report errors have an Error **errp
 *   parameter.  It should be the last parameter, except for functions
 *   taking variable arguments.

is_only_migratable() and add_blockers() have it in the middle.  Clean
them up.
