xend: Fix cleanup_domains() for suspending managed domains

When unmanaged domains with on_xend_stop="suspend" exist, managed
domains are not suspended by xend stop command.  The processing of
cleanup_domains() is aborted by exception. This patch keeps suspending
managed domains even if unmanaged domains exist.
