The command "lvcreate --type thin --snapshot ..." to create a thin
snapshot would fail.
commit d651b340e6 removed the optional
"--type thin" from the command definition "lvcreate --snapshot LV_thin",
and added --type thin as AUTOTYPE. This was correct and should not have
changed anything if all the command defs were correct, but it broke
the "lvcreate --type thin --snapshot" case. It reveals a problem in a
different command definintion: "lvcreate --type thin LV_thin" that was
missing --snapshot in its OO list.
