Shannon Nelson 215367171b i40e: don't do link_status or stats collection on every ARQ
The ARQ events cause a service_task execution, and we do a link_status
check and full stats gathering for each service_task.  However, when
there are a lot of ARQ events, such as when doing an NVM update, we end up
doing 10's if not 100's of these per second, thereby heavily abusing the
PCI bus and especially the Firmware.  This patch adds a check to keep the
service_task from running these periodic tasks more than once per second,
while still allowing quick action to service the events.
