nvme-print: Unify number base format for nsid

`nvme list` is one of the most frequently used subcommand to list up
nvme devices in the system.  `nvme list -v` prints much more detail in
it.  But, those two commands have different number base format which are
decimal and hexadecimal without any prefix (e.g., 0x) or something.

nvme list -v shows hexadecimal nsid without `0x` which means it might be
confused between decimal and hexadecimal.  To unify this, this patch
expands device NSID fields width from 8 to 10 to cover `0x` two chracters
as a prefix for both `nvme list` and `nvme list -v`.
