The IIO core handles a trigger ops with all NULL callbacks the
same as if the trigger ops itself was NULL.

Remove the empty trigger ops from the interrupt trigger driver to slightly
reduce the boilerplate code. Object size of the driver module is also
slightly reduced.

Good spot - I was kind of assuming we didn't protect all call sites
but seems that we do so good to get rid of these

Series applied to the togreg branch of iio.git and pushed out as testing
for all the normal reasons.

Thanks,

Jonathan
