KVM: nVMX: handle nested posted interrupts when apicv is disabled for L1

Browse source

commit 91a5f413af upstream.

Even when APICv is disabled for L1 it can (and, actually, is) still
available for L2, this means we need to always call
vmx_deliver_nested_posted_interrupt() when attempting an interrupt
delivery.
