staging: lustre: obd: add case LCFG_PARAM to osd_process_config

Browse source

Some proc parameters were moved from ofd to osd module and only
their symlinks were kept in ofd for interoperability/compatibility.
To process this kind of config params passed by ofd, this patch is
to do the following fixes:

 - since these parameters are not included by the static lprocfs var
   list, a pre-check is added for them to avoid "unknown param" error
   message confuses the uses. If they are matched in this check, they
   will be passed to the osd directly.
 - improve the error messages in class_process_proc_param() and
   class_process_proc_seq_param() a little.
