[PATCH] KVM: remove redundant code in kvm_arch_vm_ioctl

From: Miaohe Lin
Date: Sun Oct 20 2019 - 22:52:36 EST


If we reach here with r = 0, we will reassign r = 0
unnecesarry, then do the label set_irqchip_out work.
If we reach here with r != 0, then we will do the label
work directly. So this if statement and r = 0 assignment
is redundant.
