Intel FlexPriority maintains a "virtual TPR" register in memory(Virtual
APIC Page), APIC-access Page contains host physical address of guest APIC
page, Virtual APIC Page contains host physical address of the page stored
LAPIC registers. However, commit dc651f440f5 (KVM: nVMX: get rid of
nested_get_page()) sets the address of APIC-access Page to the vmcs field
of Virtual APIC Page which breaks the FlexPriority.
This patch fixes it by setting Virtual APIC Page to it related vmcs field.
