syscall_count, ksoftirqd_task, local_syscall_count, local_ksoftirqd_task
and local_nmi_count are totally unused (and gone from other
architectures aswell)

nmi_count() is a stub only used once in arch/ia64/kernel/irq.c, so we
can use 0 directly there.  I suspect it was added to keep irq.c in sync
with i386, but even the CONFIG_GENERIC_HARDIRQS code (<hint>which IA64
needs to be converted to</hint>) leaves /proc/interrupts output to the
architecture because it's so different over the architectures.

Deleted the code to print "NMI:" and a row of zeroes from irq.c -Tony
