resampler: Add assert to set_input/output_rate

This adds asserts to check if the implementation has an update rate
function defined for the unlikely event that some implementation forgets
to assign a update rate function we can simply bail.

It is expected from the resampling implementations to have such a
function even if the state of the resampler is completely reset.
