Jinank Jain 3fe7d6d904 hypervisor: mshv: Disable previous GHCB page before setting new one
CVM guests can configure GHCB page multiple times during it's
lifetime depending on it's requirement. For example a Linux CVM guest
configures a different GHCB page during compressed kernel boot and sets
up a new one after decompressing the kernel. As a cleanup step, VMM
should unset the previous GHCB page before registering a new one for
a particular vcpu thread.
