net: hns3: Set STATE_DOWN bit of hdev state when stopping net

BugLink: https://bugs.launchpad.net/bugs/1810457
We clear STATE_DOWN bit of hdev state when starting net, but do not set
it again when stopping net. It causes that the net is down, but hdev state
is still up. STATE_DOWN bit of hdev state should be set when stopping net.
