net: hns3: use hns3_get_ae_dev() helper to reduce the unnecessary middle layer conversion

There are too many indirection layers in the HNS3 driver code.
This issue was previously discussed with the maintainer,
who suggested adding a helper function to fix the issue.
In fact, the hns3_get_ae_dev() helper is already defined
and can fix this issue.

This patch uses hns3_get_ae_dev() helper to reduce the unnecessary
middle layer conversion. Apply it to the whole HNS3 driver.
The former discusstion can be checked from the link.
