[PATCH] UBUNTU: SAUCE: Drivers: hv: vmbus: Fix the boot issue for VBS Isolated VMs

[Tim Gardner]

From: Dexuan Cui <decui at microsoft.com>

BugLink: https://bugs.launchpad.net/bugs/1981328

In the case of VBS VMs, we also need to call the hypercall
hv_mark_gpa_visibility() to expose the vmbus_connection.monitor_pages
to Hyper-V, otherwise the VM fails to boot as a VBS VM.

The change doesn't affect SNP VMs and regular VMs.
