nvme: Fix reservation status related structs
This fixes the following issues with the reservation status structs:
1. resv10 is bytes 23:10 so it should be 14 bytes.
2. regctl_ds only supports 64 bit host IDs.
These are not currently used, but will be in this patchset which adds
support for the reservation report command.
