Subject: [PATCH] rdpsnd/pulse: Fix crashes in pulseaudio

Function pa_stream_trigger has to be called under lock to avoid
following crashes on asserts:

Assertion 'e->mainloop->n_enabled_defer_events > 0' failed at pulse/mainloop.c:257, function mainloop_defer_enable(). Aborting.
Assertion '!e->next' failed at pulsecore/queue.c:104, function pa_queue_pop(). Aborting.
Assertion 'q->front' failed at pulsecore/queue.c:81, function pa_queue_push(). Aborting.
