Stefan Metzmacher 627a785784 s3:rpc_server: make use of dcesrv_assoc_group_common_destructor() 
We need to detach dcesrv_iface_state from dcesrv_assoc_group,
if dcesrv_assoc_group is free'ed first.

Typically this doesn't happen, but it does when
rpc_worker_connection_terminated explicitly calls
talloc_unlink(conn, conn->assoc_group)
and dcesrv_iface_state_store_conn() is used.

But we better do it in all assoc_group destructors.
