Fix the comment to match what the code is doing, as explained in
the changelog of commit 86cf9e154632cb28d749db0ea47946fba8cf3f09
that introduced the change:
Commit 9458a9a1df1a4c719e24512394d548c1fc7abd22 added synchronization
of vCPU and migration operations through calling run_on_cpu operation.
However, in replay mode this synchronization is unneeded, because
I/O and vCPU threads are already synchronized.
This patch disables such synchronization for record/replay mode.
