ARM interrupts improvements.

- Fix nexus_setup_intr() abuse of setting up multiple IRQs in one go. Calling
  arm_setup_irqhandler() in loop is bogus, as there's just one cookie given
  from the caller and it is overwritten in each iteration so that only the
  last handler's cookie value prevails.

- Proper intr masking/unmasking handling: the IRQ source is masked at PIC level
  only after the last handler has been removed from the list.
