[PATCH] nfit: fix translation of command status results

[Dan Williams]

When transportation of the command completes successfully, it indicates
that the 'status' result is valid.  Fix the missed checking and
translation of the status field at the end of acpi_nfit_ctl().
Otherwise, we fail to handle reported errors and assume commands
complete successfully.
