[PATCH 5.4 03/80] Revert "svm: Add warning message for AVIC IPI invalid target"

[Greg Kroah-Hartman]

From: Sean Christopherson <seanjc@xxxxxxxxxx>

commit dd4589eee99db8f61f7b8f7df1531cad3f74a64d upstream.

Remove a WARN on an "AVIC IPI invalid target" exit, the WARN is trivial
to trigger from guest as it will fail on any destination APIC ID that
doesn't exist from the guest's perspective.

Don't bother recording anything in the kernel log, the common tracepoint
for kvm_avic_incomplete_ipi() is sufficient for debugging.

This reverts commit 37ef0c4414c9743ba7f1af4392f0a27a99649f2a.
