[PATCH 04/22] KVM: x86/hyperv: remove unnecessary mmu_is_nested() check

[Paolo Bonzini <pbonzini@redhat.com>]

Just always go through kvm_translate_gpa(), which will either invoke
the vendor check or just return hc->ingpa back.

This is a better way to fix the issue of commit 464af6fc2b1d ("KVM:
x86: check for nEPT/nNPT in slow flush hypercalls", 2026-05-03).
