x86: fix warning in arch/x86/kernel/io_apic.c
this warning: arch/x86/kernel/io_apic.c: In function ‘ir_set_msi_irq_affinity’: arch/x86/kernel/io_apic.c:3373: warning: ‘cfg’ may be used uninitialized in this function triggers because the variable was truly uninitialized. We'd crash on entering this code. Signed-off-by: Ingo Molnar <mingo@elte.hu>
