KVM: x86: move LAPIC initialization after VMCS creation
The initial reset of the local APIC is performed before the VMCS has been
created, but it tries to do a vmwrite:
vmwrite error: reg 810 value 4a00 (err 18944)
CPU: 54 PID: 38652 Comm: qemu-kvm Tainted: G W I 4.16.0-0.rc2.git0.1.fc28.x86_64 #1
Hardware name: Intel Corporation S2600CW/S2600CW, BIOS SE5C610.86B.01.01.0003.090520141303 09/05/2014
Call Trace:

Move it later, after the VMCS has been created.
