Calculation of the ANA log page size should use the
identify ctrl MNAN field
(maximum number of allowed namespaces)
not the NN (maximum valid nsid value).
An ANA-enabled controller must have a non-zero MNAN value,
see NVMe Base Specification, Figure 251,
therefore nvme_ctrlr_init_ana_log_page() may safely use MNAN.
Since NN might be much higher than MNAN,
ANA log size based on NN may results in a very large
log page and cause a failure to get ANA log,
e.g. if it is larger than the controller's MDTS.
Fix: replace cdata->nn with cdata->mnan
in nvme_ctrlr_init_ana_log_page()
