  1. nvme: skip optional id ctrl csi for versions less than 2.0.0 

    The NVME_ID_CNS_CS_CTRL command has been introduced in version 2.0.0.
However, this command returns an "Invalid Field" error when executed
on previous NVMe versions. In the case of CM6 devices, this error is
logged on the error log page. Additionally, for CM6 drives, the
reservation commands manipulated by the fenced process indirectly
trigger the NVME_ID_CNS_CS_CTRL command every few seconds, leading
to a periodic increment in the error count.

While these error entries are harmless, smartctl periodically increases
the NVMe error counts. Smartctl displays the increase in NVMe error
count due to these errors on both the console and the log file,
without providing additional information. To resolve this issue,
a simple solution is to skip the NVME_ID_CNS_CS_CTRL command if the
version is less than 2.0.0.
