net: hns3: set ops to null when unregister ad_dev
[ Upstream commit 594a81b39525f0a17e92c2e0b167ae1400650380 ]
The hclge/hclgevf and hns3 module can be unloaded independently,
when hclge/hclgevf unloaded firstly, the ops of ae_dev should
be set to NULL, otherwise it will cause an use-after-free problem.
Fixes: 38caee9d3ee8 ("net: hns3: Add support of the HNAE3 framework")
