Currently, there is a coverity defect warning about hns3 PMD driver, the
detail information as blow:
CID 289969 (#1 of 1): Unchecked return value (CHECKED_RETURN)
1. check_return: Calling rte_mp_action_register without checking return
value (as is done elsewhere 11 out of 13 times).
The problem is that missing checking the return value of calling the API
rte_mp_action_register during initialization. If registering an action
function for primary and secondary communication failed, the secondary
process can't work properly.
This patch fixes it by adding check return value of the API function
named rte_mp_action_register in the '.dev_init' implementation function
of hns3 PMD driver.
Coverity issue: 289969
Fixes: 23d4b61fee ("net/hns3: support multiple process")
