Fix memory leaks in module_audio_init_spd.
Fix memory leaks in module_audio_init_spd.

We missed these in the last round of memory leak fixes.
* Free the error variable, set when spd_audio_open fails.
Its value is set by g_strdup_printf, so we free it with g_free.
* The outputs variable is set by a call to g_strsplit.  It is a
list of strings, terminated with a NULL pointer.
As per the glib docs, we now free it using g_strfreev.
