KVM: selftests: hyperv_tlb_flush: replace NOP loop with udelay()

Browse source

Replace the open-coded NOP loop with udelay() which was added to KVM
selftests in commit 6b878cbb87 ("KVM: selftests: Add guest udelay()
utility for x86"). The NOP loop is CPU speed dependent while udelay()
provides a deterministic delay regardless of host CPU frequency.
