[PATCH net] net: hns3: call hns3_nic_net_open() while doing HNAE3_UP_CLIENT

[Huazhong Tan]

For HNAE3_DOWN_CLIENT calling hns3_nic_net_stop(), HNAE3_UP_CLIENT
should call hns3_nic_net_open(), since if the number of queue or
the map of TC has is changed before HHAE3_UP_CLIENT is called,
it will cause problem.

Also the HNS3_NIC_STATE_RESETTING flag needs to be cleared before
hns3_nic_net_open() called, and set it back while hns3_nic_net_open()
failed.

Fixes: bb6b94a896d4 ("net: hns3: Add reset interface implementation in client")
