net: hns3: prevent unnecessary MAC TNL interruption

driver inclusion
category: bugfix
bugzilla: NA
CVE: NA

MAC TNL interrupt is used to collect statistics info about
link status changing suddenly when netdev running.

But when stopping netdev, there also be a MAC TNL interrupt
which is unnecessary, and may add some noise to the statistics
info. So this patch disables it before stopping MAC.

Fixes: a6345787 ("net: hns3: Add handling of MAC tunnel interruption")
