READ_ONCE should be used when reading rings prior to accessing the

The READ_ONCE macro is used when reading rings prior to accessing the
statistics pointer. The corresponding WRITE_ONCE usage when allocating and
freeing the rings to ensure protected access was not in place. Introduce
this.

Interfaces already exist for dumping rx and tx descriptor information.
Introduce another for doing the same for xdp descriptors.
