[dpdk-dev] [PATCH v2] net/ring: remove unnecessary NULL check

[Mauricio Vasquez B <mauricio.vasquez@polito.it>]

Coverity detected this as an issue because internals->data will never be NULL,
then the check is not necessary.

Fixes: d082c0395bf6 ("ring: fix memory leak when detaching")
Coverity issue: 137873
