util: fix releasing pidfile in cleanup

Browse Source 
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.
