Skip domains on libvirt errors in get_vcpu_used()
This commit is to avoid a race condition between deletes
and creates. It is possible for a delete to remove a domain
from the list returned by _conn.listDomainsID() while
get_vcpu_used() is looping over the list. If this happens
libVirt raises a LibVirtError and sets the instance to the
ERROR state. To avoid this LibVirtError is caught and the loop
continues instead of raising the exception.
