Subject: nvme-cli: show more fields for id-ctrl
Git-commit: 176ce81b8d3784a72a2d95888ce4a6f3e205e6e6
Patch-mainline: v1.4

NVMe 1.3 inctrodues new fields such as EDSTT, DSTO, FWUG, HCTMA, MNTMT,
MXTMT, SANICAP into the idenfity controller data structure. The id-ctrl
command should print them or write them into json format. Note that
although KAS field is included in the previous NVMe 1.2.1 spec, this
patch also supports this field.
