rw_lock_create_func(): Initialize lock->writer_thread, so that Valgrind will not complain even when Valgrind instrumentation is not enabled. Flag lock->writer_thread uninitialized, so that Valgrind can complain when it is used uninitialized. rw_lock_set_writer_id_and_recursion_flag(): Revert the bogus Valgrind instrumentation that was pushed in the first attempt to fix this bug.
