[PATCH net] hinic: fix leak of ethtool RSS user configuration buffers

[Chenguang Zhao <chenguang.zhao@linux.dev>]

From: Chenguang Zhao <zhaochenguang@kylinos.cn>

rss_indir_user and rss_hkey_user are allocated in __set_rss_rxfh() when
the user configures RSS via ethtool, but hinic_remove() never frees them.
free_netdev() only releases the nic_dev structure itself, so the separately
allocated buffers are leaked on driver unload.

Free both buffers in hinic_remove() after unregister_netdev().

Fixes: 4fdc51bb4e92 ("hinic: add support for rss parameters with ethtool")
