Release a previously created equalizer instance.
    The equalizer was previously created by using L{libvlc_audio_equalizer_new}() or
    L{libvlc_audio_equalizer_new_from_preset}().
    It is safe to invoke this method with a NULL p_equalizer parameter for no effect.
    @param p_equalizer: opaque equalizer handle, or NULL.
