To use this routine effectively, add a new wrapper around ndctl_cmd_submit (called ndctl_cmd_submit_xlat) that submits the command, and also runs it through the above translator dimm_op (if one is is defined).

It is only truly an error if it returns a negative number. Several places in the library, the ndctl utility, and in test/ were simply checking for an error with "if (rc)". Fix these to only error out for negative returns.
