KVM: x86: clean/fix memory barriers in irqchip_in_kernel The memory barriers are trying to protect against concurrent RCU-based interrupt injection, but the IRQ routing table is not valid at the time kvm->arch.vpic is written. Fix this by writing kvm->arch.vpic last. kvm_destroy_pic then need not set kvm->arch.vpic to NULL; modify it to take a struct kvm_pic* and reuse it if the IOAPIC creation fails.
