[PATCH v2 5/7] migration/multifd: Remove sync processing on postcopy

[Peter Xu]

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.
