[PATCH] powerpc: Fix potential compile error irqs_disabled_flags

[Michael Neuling]

irqs_disabled_flags is #defined in linux/irqflags.h when
CONFIG_TRACE_IRQFLAGS_SUPPORT is enabled.

This fixes the case when someone needs to include both linux/irqflags.h
and asm/hw_irq.h.

I'm not sure if this is the right fix.  We could just remove
irqs_disabled_flags but I think that has the possibility of breaking
32bit.
