net: hns3: add reset check for VF updating port based VLAN
Currently hclgevf_update_port_base_vlan_info() may be called when VF is resetting, which may cause hns3_nic_net_open() being called twice unexpectedly. So fix it by adding a reset check for it, and extend critical region for rntl_lock in hclgevf_update_port_base_vlan_info().
