Disable interrupts when we enter cpu_intr() and enable them again when leaving
that function. It seems this function was intended to be called with
interrupts disabled but that is not (no longer?) the case. As a result
there were some races accessing the list of interrupt handlers and we would
leave the function with interrupts disabled if there were any interrupts
pending. This could make us end up in the idle loop with interrupts disabled,
which would "hang" the machine.
