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

Browse Source 
[ Upstream commit 2f7e489611 ]

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.
