    Fix hang on netdde crash with a nacked interrupt
    
    If netdde crashed without acknowledging the interrupt, the hardware
    might be stuck in a situation where it keeps the interrupt raised, and
    thus linux_intr keeps getting called. linux_intr should detect that we
    have removed handlers and then just disable the interrupt. Hopefully
    when the driver restarts it will reset the card, and thus the interrupt
    will stop before it enables it again.
