 * Test pthread_spin_destroy(pthread_spinlock_t * lock)
 *
 * pthread_spin_destroy() function shall destroy the spin lock
 * referenced by lock and release any resources used by the lock.
 *
 * Steps:
 * 1.  Initialize a pthread_spinlock_t object 'spinlock' with
 *     pthread_spin_init()
 * 2.  Main thread lock 'spinlock', should get the lock
 * 3.  Main thread unlock 'spinlock'
 * 4.  Main thread destroy the 'spinlock'
