net: hns3: add existence check when remove old uc mac address
When driver is in initial state, the mac_vlan table table is empty.
So the delete operation for mac address must fail. Existence check
is needed here. Otherwise, the error message will make user confused.
Fixes: 46a3df9f9718 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
