net: dql: Optimize stall information population
When Dynamic Queue Limit (DQL) is set, it always populate stall
information through dql_queue_stall(). However, this information is
only necessary if a stall threshold is set, stored in struct
dql->stall_thrs.
dql_queue_stall() is cheap, but not free, since it does have memory
barriers and so forth.
Do not call dql_queue_stall() if there is no stall threshold set, and
save some CPU cycles.
