traps: x86_64: remove trace_hardirqs_fixup from int3 handler
All exceptions are taken via interrupt gates. TRACE_IRQS_OFF is called just before entering the C code, so the irq state is known to the irq tracer at this point. No need to call trace_hardirqs_fixup. Signed-off-by: Alexander van Heukelum <heukelum@fastmail.fm> Signed-off-by: Ingo Molnar <mingo@elte.hu>
