Thomas Huth 777f53c759 Revert "migration: Simplify unqueue_page()" 
This reverts commit cfd66f30fb.

The simplification of unqueue_page() introduced a bug that sometimes
breaks migration on s390x hosts.

The problem is not fully understood yet, but since we are already in
the freeze for QEMU 7.1 and we need something working there, let's
revert this patch for the upcoming release. The optimization can be
redone later again in a proper way if necessary.
