lockdep: Add print_irqtrace_events() to __warn

Running a test on a x86_32 kernel I triggered a bug that an interrupt
disable/enable isn't being catched by lockdep. At least knowing where the
last one was found would be helpful, but the warnings that are produced do
not show this information. Even without debugging lockdep, having the WARN()
display the last place hard and soft irqs were enabled or disabled is
valuable.
