net: hns3: Fix loss of coal configuration while doing reset

[ Upstream commit e4fd75022c24eb28cc1034e97e60cecc24f325f3 ]

The user's coal configuration will be lost after reset, so the tx_coal
and rx_coal fields are added to the struct hns_nic_priv to save the coal
configuration and used to restore the user's configuration after the reset
is complete.
