[Bug 1705534] [NEW] "lvs" exits with status 0 after failing

[Jonathan Kamens]

Public bug reported:

$ sudo lvs --noheadings -o vg_name /tmp
[sudo] password for jik: 
  "/tmp": Invalid path for Logical Volume.
$ echo $?
0
$

The exit status there after I've provided an invalid logical volume path
and the program has printed an error message clearly should not be 0.
