KVM: x86: use correct APIC ID on x2APIC transition
SDM April 2015, 10.12.5 State Changes From xAPIC Mode to x2APIC Mode
• Any APIC ID value written to the memory-mapped local APIC ID register
is not preserved.
Fix it by sourcing vcpu_id (= initial APIC ID) instead of memory-mapped
APIC ID. Proper use of apic functions would result in two calls to
recalculate_apic_map(), so this patch makes a new helper.
