The hccs_get_all_port_attr() is used to obtained the attribute of all
ports on a specified DIE from firmware. However, this interface doesn't
ensure whether firmware reports the complete attribute of all ports or not.
So this patch adds the check for this.

How about changing to "failed to get the expected port number(%u) attribute.\n"?
