nvme: print a warning for when listing active namespaces fails
During the scan_work, an Identify command is issued to figure out which
namespaces are active. If this command fails, the nvme driver falls back
to scanning namespaces sequentially. In this situation, we don't see
any warnings and don't even know whether list-ns command has been failed
or not easiliy.
Printa warning when the Identify command executin fail:
[ 1.108399] nvme nvme0: Identify NS List failed (status=0x400b)
[ 1.109583] nvme0n1: detected capacity change from 0 to 1048576
