qed: Don't over-do producer cleanup for Rx

Orabug: 25477939

Before requesting the firmware to start Rx queues,
driver goes and sets the queue producer in the device to 0.
But while the producer is 32-bit, the driver currently clears 64 bits,
effectively zeroing an additional CID's producer as well.
