net: netcp: allocate buffers to desc before re-enable interrupt
Currently netcp_rxpool_refill() that refill descriptors and attached buffers to fdq while interrupt is enabled as part of NAPI poll. Doing it while interrupt is disabled could be beneficial as hardware will not be starved when CPU is busy with processing interrupt.
