We need to be able to disable the link state interrupt when
the device is brought down. We used to just free the IRQ
at the beginning of .ndo_stop(). As we now move towards
more ordered .ndo_open()/.ndo_stop() paths LSC allocation
should be placed in the "allocate resource" section.
Since the IRQ can't be freed early in .ndo_stop(), it is
disabled instead.
