    xen/arm: Clear the IRQ_GUEST bit in desc->status when releasing an IRQ
    
    While adding support for guest domU IRQs, I noticed that release_irq did
    not clear the IRQ_GUEST bit in the IRQ's desc->status field.
    This is probably not a big deal since not many situations are likely to 
arise
    where an IRQ is sometimes host and sometimes guest.
