ix86: Fix build failure when !CONFIG_X86_IO_APIC

mp_should_keep_irq() isn't really IO-APIC related, and
considering that it's being used solely in arch/x86/pci/ likely
both declaration and definition got misplaced even without
considering the resulting build failure:

.../arch/x86/pci/irq.c: In function ‘pirq_disable_irq’:
.../arch/x86/pci/irq.c:1259: error: implicit declaration of function ‘mp_should_keep_irq’
make[3]: *** [arch/x86/pci/irq.o] Error 1

Move them to better places.
