x86: irq: Fix placement of mp_should_keep_irq()
While f3761db164 ("x86, irq: Fix build error caused by 9eabc99a635a77cbf09") addressed the original build problem, declaration, inline stub, and definition still seem misplaced: It isn't really IO-APIC related, and it's being used solely in arch/x86/pci/. This also means stubbing it out when !CONFIG_X86_IO_APIC was at least questionable.
