name ofd device type "ofd" instead of "obdfilter"

I can easily add this work on top of the ofd patch for <a href="https://jira.whamcloud.com/browse/LU-3319" title="Adapt to 3.10 upstream kernel proc_dir_entry change" class="issue-link" data-issue-key="LU-3319"><del>LU-3319</del></a>.</p> <p>Patch at <a href="http://review.whamcloud.com/#/c/4618" class="external-link" target="_blank" rel="nofollow noopener">http://review.whamcloud.com/#/c/4618</a></p> <p>Got around to updating the patch. With this patch the obd_type is now "ost" instead of obdfilter. Also fixed up the OSS / oss proc handling to match what mdt / MDS does. So proc is updated correctly and the obd_device is handled right but the file system writes to the log the OST device as obdfilter. Changing that will break down grade abilities. Well I will discuss that in <a href="https://jira.whamcloud.com/browse/LU-2161" title="Remove last traces of obdfilter" class="issue-link" data-issue-key="LU-2161">LU-2161</a> on how to handle this.</p> <p>James Simmons (uja.ornl@yahoo.com) uploaded a new patch: <a href="https://review.whamcloud.com/32475" class="external-link" target="_blank" rel="nofollow noopener">https://review.whamcloud.com/32475</a><br/> Subject: <a href="https://jira.whamcloud.com/browse/LU-2096" title="name ofd device type &quot;ofd&quot; instead of &quot;obdfilter&quot;" class="issue-link" data-issue-key="LU-2096">LU-2096</a> lprocfs: symlinks for forward compatibility<br/> Project: fs/lustre-release<br/> Branch: master<br/> Current Patch Set: 1<br/> Commit: e6d499b53a54c5624dc5f9c913876865b7e356fd</p> Related LU-8066 LU-3300 LU-2161 Development Rank 1|hzv587: Rank (Obsolete) 4380
