sparc64: Fix hardirq tracing in trap return path.
[ Upstream commit 28a1f533ae8606020238b840b82ae70a3f87609e ]
We can overflow the hardirq stack if we set the %pil here
so early, just let the normal control flow do it.
This is fine as we are allowed to do the actual IRQ enable
at any point after we call trace_hardirqs_on.
