nvme: use command set independent id ns if available

Browse source

The NVMe 2.0 specification adds an independent identify namespace
data structure that contains generic attributes that apply to all
namespace types. Some attributes carry over from the NVM command set
identify namespace data structure, and others are new.

Currently, the data structure only considered when CRIMS is enabled or
when the namespace type is key-value.

However, the independent namespace data structure is mandatory for
devices that implement features from the 2.0+ specification. Therefore,
we can check this data structure first. If unavailable, retrieve the
generic attributes from the NVM command set identify namespace data
structure.
