It's not just not used, it's not present. Let me try to rephrase the
commit message a bit:

"
Commit 0c899c25d754 ("KVM: x86: do not attempt TSC synchronization on
guest writes") renamed kvm_write_tsc() to kvm_synchronize_tsc() and made
it 'static'. Remove the leftover declaration from x86.h

Fixes: 0c899c25d754 ("KVM: x86: do not attempt TSC synchronization on
guest writes")
"

The subject line should probably also get adjusted like
"KVM: x86: remove dangling declaration of kvm_write_tsc()"
