x86/irq: Fix kbuild warning in smp_irq_move_cleanup_interrupt()

Fengguang Wu's 0day kernel build service reported the following build warning:

  arch/x86/kernel/apic/io_apic.c:2211
  smp_irq_move_cleanup_interrupt() warn: always true condition '(irq <= -1) => (0-u32max <= (-1))'

because irq is defined as an unsigned int instead of an int.
Fix this trivial error by redefining irq as a signed int.  The
remaining consumers of the int are okay.
