KVM: x86: Plumb in the vCPU to kvm_x86_ops.hwapic_isr_update()
[ Upstream commit 76bce9f10162cd4b36ac0b7889649b22baf70ebd ]
Pass the target vCPU to the hwapic_isr_update() vendor hook so that VMX
can defer the update until after nested VM-Exit if an EOI for L1's vAPIC
occurs while L2 is active.
Note, commit d39850f57d21 ("KVM: x86: Drop @vcpu parameter from
kvm_x86_ops.hwapic_isr_update()") removed the parameter with the
justification that doing so "allows for a decent amount of (future)
cleanup in the APIC code", but it's not at all clear what cleanup was
intended, or if it was ever realized.
No functional change intended.
