net: hns: fix for promisc mode in HNS driver
If set promisc mode when there is some traffic, The service nic will
cause system halted. We reserve the last 6 tcam entry for the 6 ports.
If promisc mode is enabled, we can config the relative tcam as fuzzy
matching and set to be valid, or set the tcam to be invalid
