Description:
The pthread_spin_destroy() function destroys the thread spinlock spinner, releasing its resources.
Once you've destroyed the spinlock, don't use it again until you've reinitialized it by calling pthread_spin_init().
Calling pthread_spin_destroy() gives undefined results when a thread has spinner locked or when spinner isn't initialized.

- Success.
- EBUSY
- The thread spinlock spinner is in use by another thread and can't be destroyed.
- EINVAL
- Invalid pthread_spinlock_t object spinner.
