nvmet: use NVMET_MAX_NAMESPACES to set nn value
For Spec regarding MNAN value:-
If the controller supports Asymmetric Namespace Access Reporting, then
this field shall be set to a non-zero value that is less than or equal
to the NN value.
Instead of using subsys->max_nsid that gets calculated dynamically,
use NVMET_MAX_NAMESPACES value to report NN. This way we will maintain
the MNAN value spec compliant with NN.
Without this patch, code results in the following error :-
[337976.409142] nvme nvme1: Invalid MNAN value 1024
