If an I/O failed by ANA error, the corresponding ANA state might be
out of date. In the following patches, for this case, read the latest
ANA log page and update the ANA state. Such reading ANA log page may be
done on multiple threads concurrently including AER ANA change.
Hence protect ANA log page by adding an new flag ana_log_page_updating
to struct nvme_ctrlr and using it.
