[][kernel][common][eth][Fix rcu_sched detected stall issue during LRO stress test]
[Description]
Fix rcu_sched detected stall issue during LRO stress test.
If both the RSS and LRO interrupts are activated at the same time,
it could lead to an incorrect evaluation of the current check condition.
This situation may lead to multiple executions of the napi_sched_prep()
function for a specific RX ring, ultimately causing preventing the
rescheduling of the mtk_napi_rx task.
Without this patch, the rcu_sched may have detected a CPU stall during
the LRO stress test.
