net/hns3: clear residual hardware configurations on init

When the last driver exits abnormally, for example, it is killed by
'kill -9', it may be too late to clear the configuration and cause the
configuration to remain. Therefore, to ensure that the hardware
environment is clean during initialization, the PF driver actively clear
the hardware environment during initialization, including PF and
corresponding VFs' vlan, mac, flow table configurations, etc.
