nvme-cli: bug-fix: use right file name for perror.

Hi,

Looks like earlier patch did not go into the nvme-cli.

Resending the same patch again, earlier patch will not be applicable after recent commits.

Regards,
-Chaitanya

Use right file descriptor while printing an error, when --metadata option is used for read/write commands.
