posix: posix_health_check_thread_proc crash due to priv is NULL
Problem: posix_fini sends a cancellation request to health_check
         thread and cleanup priv without ensuring health_check thread
         is running
Solution: Make health_check && disk_space thread joinable and call
          gf_thread_cleanup_xint to wait unless thread is not finished
