This is not needed, as colo primary side everything is more or less
a new migration for every checkpoint.
Also, we only enter colo mode after the precopy migration is finished
so this if is always taken. Still add an assert just in case.

And probably for zero_page and xbzrle (when factored out in it's own

don't use it, but it should be easy to do by just letting xbzlre try
to handle the page before multifd.
There shouldn't be any incompatibilities other than that, as long as
xbzlre sees the pages before multifd and the zero-page case is still
handled the old way.

There has never been tests for migration with compress enabled.
Add suitable tests, testing with compress-wait-thread = false

Make compression interfaces take send_queued_data() as an argument.
Remove save_page_use_compression() from flush_compressed_data().
This removes the last ram.c dependency from the core compress code.
