hv: fix Service VM EPT mapping upper bound

Browse Source 
On some platforms, the last e820 entry may not be of type E820_TYPE_RAM,
such as E820_TYPE_ACPI_NVS which may also be used by Service VM.
So we need take all e820 entry types into account when finding the upper
bound of Service VM EPT mapping.
