[PATCH] ARM: remove the last few uses of do_bad_IRQ()

[PATCH] ARM: remove the last few uses of do_bad_IRQ()

[Ethan Nelson-Moore]

The do_bad_IRQ() macro simply calls handle_bad_irq() with a lock around
it. It also carries a comment stating that uses of it should be
replaced. According to commit aec0095653cd ("irqchip: gic: Call
handle_bad_irq() directly"), which replaced another use of
do_bad_IRQ(), locking the IRQ descriptor is not necessary for error
reporting. Therefore, replace all uses of do_bad_IRQ() with calls to
handle_bad_irq() and remove do_bad_IRQ().
