Both drivers provide both sample_new and sample_free, and it makes no sense to pretend that they could not. In fact, load_data() would already crash if sample_new was null. So remove the remaining null checks.
Contrary to that, the emu10k1 driver actually has a null sample_reset, though I'm not convinced that this inconsistency is justified.
