[PATCH] i386, nmi: signed vs unsigned mixup

[Jesper Juhl <jesper.juhl@gmail.com>]

In arch/i386/kernel/nmi.c::nmi_watchdog_tick(), the variable `sum' is 
of type "int" but it's used to store the result of 
per_cpu(irq_stat, cpu).apic_timer_irqs which is an "unsigned int", it's
also later compared to last_irq_sums[cpu] which is also an 
"unsigned int", so `sum' really ought to be unsigned itself.
This small patch makes that change.
