[libvirt] [PATCH] sanlock: fix memory leak
Detected by Coverity. The only way to get to error_unlink is if
path was successfully assigned, so the if was useless. Meanwhile,
there was a return statement that did not free path.
* src/locking/lock_driver_sanlock.c
(virLockManagerSanlockSetupLockspace): Fix mem-leak, and drop
useless if.
