[PATCH v2 2/3] KVM: nVMX: Don't clobber VM-Entry instruction length when saving soft INTn

[ma.mandourr@gmail.com]

From: Mahmoud Abumandour <ma.mandourr@gmail.com>

When a nested VM-Exit occurs while L2 is vectoring a software interrupt,
save the INTn's length in vmcs12's VM-Exit instruction length, as is
done for software exceptions, instead of VM-Entry instruction length.
