This commit does not introduce new features, just integrate some common
logic into helper functions to reduce the same logic and increase code
reuse, include queue stop and queue close logic, will be used when NFP
net stop and close.
queue stop: reset queue
queue close: reset and release queue
Modify NFP net stop and close function, use helper function to stop
and close queue instead of before logic.
