net: hns3: fix RoCE calling the wrong function problem

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

----------------------------

In hnae3.h, if the function is not for test, the definition must before
CONFIG_HNS3_TEST! Because RoCE will use hnae3.h, and it won't set
CONFIG_HNS3_TEST, that may cause RoCE calling the wrong function.
