pulsecore: thread-posix.c: remove unnecessary assignment

pthread_create(&t->id, NULL, internal_thread_func, t) already assigns the t->id parameter during the thread construction. There shouldn't be need to redo this again.

If the system is configured with the thread sanitizer, with meson: 'meson -Db_sanitize=thread', it's apparent that the unnecessary assignment only causes potential trouble:
