[lustre-devel] [PATCH v2 26/29] lustre: obdclass: remove unnecessary code from lustre_init_lsi()

From: NeilBrown <neilb at suse.com>

After allocating a struct with kzalloc, there is no value
in setting a few of the fields to zero.

And as all fields were zero, it must be safe to kfree lmd_exclude,
whether lmd_exclude_count is zero or not.
