sparseirq, powerpc/cell: fix unused variable warning in interrupt.c

This new compiler warning:

   arch/powerpc/platforms/cell/interrupt.c: In function 'handle_iic_irq':
   arch/powerpc/platforms/cell/interrupt.c:240: warning: unused variable 'cpu'

Triggers because the local variable 'cpu' became unused due to commit:

   dee4102: sparseirq: use kstat_irqs_cpu instead

Remove the variable.
