Subject: nvme: get_ns_id command fails on nvme device
X-Git-Tag: v2.0-rc4~5^2

nvme: get_ns_id command fails on nvme device

The get-ns-id command currently prints the perror status for a
given nvme device rather than its nsid. Fix this by properly
checking the return status of the nvme_get_nsid() function.
