net: hns3: do not schedule the periodical task when reset fail

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

We need to update some port info and to config some configurations to HW
in a periodical task per second, by setting registers from driver to WH.
If reset had fail, HW will not response the CMD and driver will generate
a warning print. In this case, the periodical task shouldn't schedule.
This patch fixes it.
