[PATCH V2 net-next 04/10] net: hns3: change GFP flag during lock period

[Huazhong Tan]

From: Yufeng Mo <moyuf...@huawei.com>

When allocating memory, the GFP_KERNEL cannot be used during the
spin_lock period. This is because it may cause scheduling when holding
spin_lock. This patch changes GFP flag to GFP_ATOMIC in this case.

Fixes: dd74f815dd41 ("net: hns3: Add support for rule add/delete for flow 
director")
