Subject: [PATCH net-next 2/7] net: hns3: skip periodic service task if reset failed

From: Guangbin Huang <huangguangbin2@...wei.com>

When reset fails, if there are some pending jobs for the periodic
service task, it does not do anything except print error each
time the task is scheduled. So skip the periodic service task if
reset failed.
