[PATCH net-next 1/5] net: hns3: remove always exist devlink pointer check

[Leon Romanovsky]

From: Leon Romanovsky <leonro@xxxxxxxxxx>

The devlink pointer always exists after hclge_devlink_init() succeed.
Remove that check together with NULL setting after release and ensure
that devlink_register is last command prior to call to devlink_reload_enable().

Fixes: b741269b2759 ("net: hns3: add support for registering devlink for PF")
