commit f793c23ebbe5afd1cabf4a42a3a297022213756f upstream. To use the virtual counters from the host, we need to ensure that CNTVOFF doesn't change unexpectedly. When we change to a guest, we replace the host's CNTVOFF, but we don't restore it when returning to the host. As the host sets CNTVOFF to zero, and never changes it, we can simply zero CNTVOFF when returning to the host. This patch adds said zeroing to the return to host path.
