[linux-lvm] [PATCH] lvdisplay: dispaly correct status on linear type

[heming.zhao at suse.com]

Same as the commit writing, this commit is code enhancement not bugfix.

Last commit 1d0dc74f9147e3c1f3681efa4166cbe2edcb6571 had been verified by one of suse customer.
They did test for types: mirror, raid0, raid1, raid5, linear.

For this commit, I only verified linear & raid cases. I have little experience with type: snapshot, thin, vdo, cache etc. So I am not sure whether this commit contains any bug when LV type is not linear & raid.
