[PATCH v3 10/28] KVM: SVM: Compute dest based on sender's x2APIC status for AVIC kick

[Sean Christopherson]

Compute the destination from ICRH using the sender's x2APIC status, not
each (potential) target's x2APIC status.

Fixes: c514d3a348ac ("KVM: SVM: Update avic_kick_target_vcpus to support 32-bit APIC ID")
