eal/windows: fix data race when creating threads

eal_thread_loop() uses lcore_config[i].thread_id,
which is stored upon the return from CreateThread().
Per documentation, eal_thread_loop() can start
before CreateThread() returns and the ID is stored.

Create lcore worker threads suspended and then subsequently resume to
allow &lcore_config[i].thread_id be stored before eal_thread_loop
execution.
