[PATCH] fix alt-sysrq deadlock
__handle_sysrq was modified to do a spin_lock_irqsave so we were entering
smp_send_stop with interrupts. So reenable interrupts to prevent the
possible smp_call_function() deadlock.
(It's still deadlocky if the sysrq handler is against called via an
interrupt from a different device, but that seems unlikely).
