s3:smb2_lock: always use tevent_req_defer_callback() if we go async
process_blocking_lock_queue_smb2() can call reprocess_blocked_smb2_lock()
multiple times, which results in multiple tevent_req_done() calls.
As we could disconnect the connection from there,
process_blocking_lock_queue_smb2() could crash as the local state might be
destroyed.
