NVMe: Namespace IDs are unsigned
The 'Number of Namespaces' read from the device was being treated as signed, which would cause us to not scan any namespaces for a device with more than 2 billion namespaces. That led to noticing that the namespace ID was also being treated as signed, which could lead to the result from NVME_IOCTL_ID being treated as an error code.
