migration: Unify failure check for migrate_add_blocker()
Most callers check the return value. Some check whether it set an error. Functionally equivalent, but the former tends to be easier on the eyes, so do that everywhere. Prior art: commit c6ecec43b2 "qemu-option: Check return value instead of @err where convenient".
