net: hns3: fix incorrect return value/type of some functions

Browse Source 
There are some functions that, when they fail to send the command,
need to return the corresponding error value to its caller.

Fixes: 46a3df9f97 ("net: hns3: Add HNS3 Acceleration Engine & Compatibility Layer Support")
Fixes: 681ec3999b ("net: hns3: fix for vlan table lost problem when resetting")
