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

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.
