nvme: always issue I/O Command Set specific Identify Namespace
Currently, the I/O Command Set specific Identify Namespace structure is
only fetched for controllers that support extended LBA formats. This is
because struct nvme_id_ns_nvm is only used by nvme_configure_pi_elbas(),
which is only called when the ELBAS bit is set in the CTRATT field of
the Identify Controller structure.
However, the I/O Command Set specific Identify Namespace structure will
soon be used in nvme_update_disk_info(), so always try to obtain it in
nvme_update_ns_info_block(). This Identify structure is first defined in
NVMe spec version 2.0, but controllers reporting older versions could
still implement it.
