tools/testing/nvdimm: fix return code for unimplemented commands
The implementation for the new "DIMM Flags" DSM relies on the -ENOTTY return code to indicate that the flags are unimplimented and to fall back to a safe default. As is the -ENXIO error code erroneoously indicates to fail enabling a BLK region. Signed-off-by: Dan Williams <dan.j.williams@intel.com>
