[LUDOC-271] Wrong documentation for DNE in admin manual

Description

At top of page 82 of the Lustre admin guide (https://build.hpdd.intel.com/job/lustre-manual/lastSuccessfulBuild/artifact/lustre_manual.pdf) the instruction for enabling DNE are wrong. They should read as:

To relax this restriction and enable remote sub-directories off any MDT, an administrator must issue the command lctl set_param -n mdt.{MDT-device-name}.enable_remote_dir=1.

Existing commands work as expected to permanently change the settings.

The instructions also need to be run on the MDS for that MDT when there are multiple MDSs (instead of the mgs).
The instructions should be:

.....To relax this restriction and enable remote sub-directories off any MDT, an administrator must issue the following command on the MDS:
mds# lctl set_param mdt.{MDT-device-name}.enable_remote_dir=1

For Lustre filesystem 'testfs', the command executed is:
mds1# lctl set_param mdt.testfs-MDT0001.enable_remote_dir=1

To verify the configuration setting execute the following command on any MDS:
mds# lctl get_param mdt.*.enable_remote_dir

Andreas: Sure - I'll walk though each of the steps and make sure they are correct and the captured output from commands is also still correct.

[Andreas Dilger]

Joe, this looks like a simple one to fix?
