libnvdimm, nfit: centralize command status translation
The return value from an 'ndctl_fn' reports the command execution status, i.e. was the command properly formatted and was it successfully submitted to the bus provider. The new 'cmd_rc' parameter allows the bus provider to communicate command specific results, translated into common error codes. Convert the ARS commands to this scheme to: 1/ Consolidate status reporting 2/ Prepare for for expanding ars unit test cases 3/ Make the implementation more generic Cc: Vishal Verma <vishal.l.verma@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
