[PULL,06/25] migration/multifd: Remove sync processing on postcopy

Multifd never worked with postcopy, at least yet so far.

Remove the sync processing there, because it's confusing, and they should
never appear.  Now if RAM_SAVE_FLAG_MULTIFD_FLUSH is observed, we fail hard
instead of trying to invoke multifd code.
