[PATCH v2 6/8] KVM: x86: Use wbinvd_on_cpu() instead of an open-coded equivalent

[Sean Christopherson]

Use wbinvd_on_cpu() to target a single CPU instead of open-coding an
equivalent.  In addition to deduplicating code, this will allow removing
KVM's wbinvd_ipi() once the other usage is gone.

No functional change intended.
