LDom resource calls clean entry point when primary domain is gracefully shut down

LDom agent sets failure policy of the guest domain to stop when primary domain stops. Thus when primary domain is shut down, guest domain is stopped. Moreover, when primary domain is shutdown, ldmd daemon is stopped abruptly and LDom configuration cannot be read. These operations are not under VCS control and VCS may call clean entry point.

Workaround: No workaround.
