soc: hisilicon: kunpeng_hccs: Add the check for obtaining complete port attribute

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