ALSA: ens1370: Remove always NULL parameters

The various PCM and MIDI allocation functions in this driver take a pointer
to a pointer of a PCM/MIDI object where if this parameter is provided the
newly allocated object is stored. All callers pass NULL though, so remove
the parameter. This makes the code a bit shorter and cleaner.
