net: hns3: Fixes the error legs in hclge_init_ae_dev function

Browse Source 
This patch fixes some of the missed error legs in the initialization
function of the ae device. This might cause leaks in case of failure.

Fixes: 46a3df9f97 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer
Support")
