KVM: x86: Move TSC reset out of vmcb_init
commit 47008cd887c1836bcadda123ba73e1863de7a6c4 upstream.
The VMCB is reset whenever we receive a startup IPI, so Linux is setting
TSC back to zero happens very late in the boot process and destabilizing
the TSC. Instead, just set TSC to zero once at VCPU creation time.
Why the separate patch? So git-bisect is your friend.
