Since we are storing the mem_zone address for each ring created,
we are freeing the same address multiple times.
For example the memory zone created for Rx is being freed during
Rx ring cleanup, AGG ring cleanup and CQ cleanup.
Avoid this by storing the memory zone address in RXQ instead and
free it as a part of queue_release dev_op.
In the same way do the same for TX queues as well.
