Re: [libvirt] [PATCH] util: fix releasing pidfile in cleanup

Coverity found out the very obvious problem in the code. That is that virPidFileReleasePath() was called only if virPidFileAcquirePath() returned 0. But virPidFileAcquirePath() doesn't return only 0 on success, but the FD that needs to be closed.
