When stopping an audio voice, call the audio backend's fini method before calling audio_pcm_hw_free_resources_ rather than afterwards. This allows backends which use helper threads (like pulseaudio) to terminate those threads before the conv_buf or mix_buf are freed and avoids race conditions where the helper may access a NULL pointer or freed memory.
