webadmin: Fixed VM moving between clusters error.

When moving vm between clusters(Hosts from different clusters), an
error message would appear saying:
ACTION_TYPE_CPU_PROFILE_NOT_MATCH_CLUSTER

But, after closing the message the vm would move to the other cluster
as meant. This bug was fixed and now no error message appears.
