[PATCH -mm] genirq: revert noisyness on spurious interrupts

[Thomas Gleixner <tglx@linutronix.de>]

Revert a leftover from the backed out i386 -> genirq conversion. This
led to noisy printk outputs about spurious interrupts. Move it back to
original behaviour. The handling of those spurious interrupts needs more
thought and should be fixed with the full genirq conversion of
i386/x86_64.
