net: hns3: improve the unused_tuple parameter setting

Browse Source 
Currently, when the tc tool is used to set flow table rules, the IP address
and MAC address can be configured separately, for example, src_xx or dst_xx
can be configured separately.

Therefore, the driver needs to check whether the mask is all zero in
keys, such as FLOW_DISSECTOR_KEY_IPV4_ADDRS, FLOW_DISSECTOR_KEY_IPV6_ADDRS,
and FLOW_DISSECTOR_KEY_ETH_ADDRS.
If the mask is all zero, the tuple is not configured.
In this case, the driver adds the tuple to unused_tuple.
