threaded-mainloop: Properly initialise m->n_waiting_for_accept to prevent deadlock

Compiler optimisations have been seen to initialise
m->n_waiting_for_accept to a positive non-zero value, so the while() in
pa_threaded_mainloop_signal() never proceeds. Fix this by properly
initializing m->n_waiting_for_accept in pa_threaded_mainloop_new().

Patch from Iain Bucław.
