add path to nvme list
In SPDK project (spdk.io) it is possible to represent
devices using CUSE as character devices in "/dev/spdk/" directory.
No sysfs entries are generated for those devices.
nvme-cli default behavior is to scan the sysfs for entries on
newer kernels. Previously legacy_list() was used to determine
the topology, but that worked only on "/dev/" path.
To enable listing SPDK devices following changes were made:
- pass path parameter to list command
- before checking sysfs, check the path using legacy_list()
- expand arguments of scan_subsystems and related functions to accept the path

fix dsm and copy range setup

directly and convert the individual values as part of calling the

this for DSM as well since it breaks on systems where int is not 32
