audio: Fix a race with the audioringbuffer thread

I think I found a race problem occurring in some rare situations, in the
audioringbuffer thread, when the src->thread variable is used in the
audioringbuffer thread _before_ it is updated in the parent thread with
src->thread = g_thread_try_new(...). The same situation may probably happen in
sink too, even if I only observed the problem in the gstaudiosrc myself.
