Huisong Li 1042ed401f net/hns3: fix restore filter function input 
This 'hns3_restore_filter' is an internal interface of driver.
Currently, it uses 'struct rte_eth_dev *dev' as input parameter,
This is inconvenient for the function to call in driver because
caller has to obtain its device address by global variable
'rte_eth_devices[]'. Fix the input of this function.

Fixes: 920be799db ("net/hns3: fix RSS indirection table configuration")
