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
