From: Fuyun Liang <liangfuyun1@huawei.com>

If hclge.ko has not been inserted, the value of ret always is zero
in hnae3_register_ae_dev. If hclge.ko has been inserted, the value
of ret is zero or non zero. Different execution ways have different
results. It is confusing.

The ae_dev which is initialized failed can be reinitialized when we
remove hclge.ko and insert it again. For the case initializing client
instance, it is just like the case initializing ae_dev. The main function
of hnae3_register_ae_dev is adding the ae_dev to ad_dev list. Because
adding ae_dev is always ok, we does not need to return any in this
function.

This patch changes the return type of hnae3_register_ae_dev from int
to void.
