lvrename: fix lockd LV locking

Browse Source 
lvrename should not be done if the LV is active on another host.
This check was mistakenly removed when the code was changed to
use LV uuids in locks rather than LV names.

* active on another host. This requests a transient LV lock.
* If the LV is active, a persistent LV lock already exists in
* lvmlockd, and the transient lock request does nothing.
* If the LV is not active, then no LV lock exists and the transient
* lock request acquires the LV lock (or fails). The transient lock
* is automatically released when the command exits.
